Good articles start with introductions, continue with a clear structure, and end with standard appendices such as references and related articles.

Articles start with a lead section (WP:CREATELEAD) summarising the most important points of the topic. The lead section is the first part of the article; it comes above the first header, and may contain a lead image which is representative of the topic, and/or an infobox that provides a few key facts, often statistical, such as dates and measurements.

The lead should stand on its own as a concise overview of the article's topic, identifying the topic, establishing context, and explaining why the topic is notable. The first few sentences should mention the most notable features of the article's subject – the essential facts that every reader should know. Significant information should not appear in the lead if it is not covered in the remainder of the article; the article should provide further details on all the things mentioned in the lead. Each major section in the article should be represented with an appropriate summary in the lead, including any prominent controversies; but be careful not to violate WP:Neutral point of view by giving undue attention to less important controversies, information, or praise in the lead section. As in the body of the article itself, the emphasis given to material in the lead should roughly reflect its importance to the topic, according to reliable, published sources.

Lead sections generally contain no more than about 400 words. Citations are usually but not always optional; see WP:CITELEAD.

Paragraphs should be short enough to be readable, but long enough to develop an idea. Paragraphs should deal with a particular point or idea, and all the sentences within that paragraph should revolve around the same topic. When the topic changes, a new paragraph should be started. Overly long paragraphs should usually be split up.

Some paragraphs are really tables or lists in disguise. They should be rewritten as prose or converted to their unmasked form. Wikipedia:When to use tables and Wikipedia:Embedded list offer guidance on the proper use of these elements.

Headings help clarify articles and create a structure shown in the table of contents. To learn about how the MediaWiki software uses sections, see Help:Section.

Headings are hierarchical. The article's title uses a level 1 heading, so you should start with a level 2 heading (==Heading==) and follow it with lower levels: ===Subheading===, ====Subsubheading====, and so forth. Whether extensive subtopics should be kept on one page or moved to individual pages is a matter of personal judgment. See also below under § Summary style.

Headings should not contain links. This is because headings in themselves introduce information and let the reader know what subtopics will be presented; links to other articles should be incorporated in the text of the section.

If the article can be illustrated with pictures, find an appropriate place to position these images, where they relate closely to text they illustrate. For more information on using pictures, see Wikipedia:Layout § Images and Wikipedia:Picture tutorial.

As explained in more detail at Wikipedia:Manual of Style/Layout § Standard appendices and footers, optional appendix sections containing the following information may appear after the body of the article in the following order:

1. A list of books or other works created by the subject of the article (works)
2. A list of internal "wikilinks" to related Wikipedia articles (see also)
3. Notes and references (notes, footnotes, or references)
4. A list of recommended relevant books, articles, or other publications that have not been used as sources (further reading)
5. A list of recommended relevant websites that have not been used as sources (external links).

With some exceptions, any links to sister projects appear in further reading or external links sections. Succession boxes and navigational footers go at the end of the article, following the last appendix section, but preceding the category and interwiki templates.

Well-developed articles typically contain between 2,000 and 5,000 words, though some need to be larger. Excessively large articles can be split into smaller articles to improve readability and ease of editing, or may require trimming to remain concise. The headed sub-section should be retained, with a concise version of what has been removed under an italicized header, such as Main article: History of Ruritania (a list of templates used to create these headers is available at Category:Wikipedia page-section templates). Otherwise, context is lost and the general treatment suffers. Each article on a subtopic should be written as a stand-alone article—that is, it should make sense without reading the main article.

When a subject is large (e.g., World War II) and has many sub articles, try to balance the main article. Do not put undue weight into one part of an article at the cost of other parts. In shorter articles, if one subtopic has much more text than another subtopic, that may be an indication the subtopic should have its own page, with only a summary presented on the main page.

Wikipedia articles tend to grow in a way that leads to the natural creation of new articles. The text of any article consists of a sequence of related but distinct subtopics. When there is enough text in a given subtopic to merit its own article, that text can be summarized in the present article and a link provided to the more detailed article. Cricket is an example of an article covering subtopics: it is divided into subsections that give an overview of the sport, with each subsection leading to one or more subtopic articles.

Two styles, closely related and not mutually exclusive, tend to be used for Wikipedia articles. The tone, however, should always remain formal, impersonal, and dispassionate.

These styles are

• Summary style, which is the arrangement of a broad topic into a main article and side articles, each with subtopical sections, and
• Inverted pyramid style (or news style), which places key information at the top, followed by supporting material and details, with background information at the bottom.

A feature of both styles, and of all Wikipedia articles, is the presence of the lead section, a summarizing overview of the most important facts about the topic. The infobox template found at the top of many articles is a further distillation of key points.

Summary style may apply both across a category of articles and within an article. Material is grouped and divided into sections that logically form discrete subtopics, and which over time may spin off to separate articles in order to prevent excessive article length as the main article grows. As each subtopic is spun off, a concise summary of it is left behind with a pointer (usually using the {{Main}} template) to the new side article.

There are three main advantages to using summary style:

• Different readers want varying amounts of detail, and this style permits them to choose how much they are exposed to. Some readers need just a quick summary and are satisfied by the lead section; others seek a moderate amount of info, and will find the main article suitable to their needs; yet others want a lot of detail, and will be interested in reading the side articles.
• An article that is too long becomes tedious to read. Progressively summarizing and spinning off material avoids overwhelming the reader with too much text at once.
• An excessively detailed article is often one that repeats itself or exhibits writing that could be more concise. The development of summary-style articles tends to naturally clear out redundancy and bloat, though in a multi-article topic this comes at the cost of some necessary cross-article redundancy (i.e., a summary of one article in another).

The exact organizing principle of a particular summary-style article is highly context-dependent, with various options, such as chronological, geographical, and alphabetical (primarily in lists), among others.

Some examples of summary style are the former featured articles Association football and Music of the Lesser Antilles.

Some articles follow the inverted pyramid structure of journalism, which can be seen in news articles that get directly to the point. The main feature of the inverted pyramid is placement of important information first, with a decreasing importance as the article advances. Originally developed so that the editors could cut from the bottom to fit an item into the available layout space, this style encourages brevity and prioritizes information, because many people expect to find important material early, and less important information later, where interest decreases.

Encyclopedia articles are not required to be in inverted pyramid order and often are not, especially if a chronological, geographical, or other structure is a better fit. However, a familiarity with this convention may help in planning the style and layout of an article for which this approach is a good fit. Common examples are short-term events, concise biographies of persons notable for only one thing, and other articles where there are not likely to be many logical subtopics, but a number of facts to prioritize for the reader.

The lead section and many stub articles use the inverted pyramid approach at least in part. Consequently, many articles begin as inverted-pyramid pieces and add features of summary style later as the article develops. Individual sections of an article can also use the inverted pyramid structure so that readers skimming the sections get the most important information first before moving to the next section.

Wikipedia is not a manual, guidebook, textbook, or scientific journal. Articles and other encyclopedic content should be written in a formal tone. Standards for formal tone vary depending upon the subject matter but should usually match the style used in Featured- and Good-class articles in the same category. Encyclopedic writing has a fairly academic approach, while remaining clear and understandable. Formal tone means that the article should not be written using argot, slang, colloquialisms, doublespeak, legalese, or jargon that is unintelligible to an average reader; it means that the English language should be used in a businesslike manner (e.g. use "feel" or "atmosphere" instead of "vibes").

Articles should not be written from a first-person (I/me/my and we/us/our) or second-person (you and your) point of view. The first person often inappropriately implies a point of view inconsistent with the neutrality policy, while the second person is associated with the step-by-step instructions of a how-to guide, which Wikipedia is not. First- and second-person pronouns should ordinarily be used only in attributed direct quotations relevant to the subject of the article.

There can be exceptions to these guidelines. For instance, the "inclusive we" widely used in professional mathematics writing is sometimes used to present and explain examples in articles, although discouraged on Wikipedia even for that subject.

Avoid gendered language when possible. For example, write the children or the actors rather than the boys and girls or the actors and actresses. Use the singular they instead of the generic he, or write sentences in plural. See Wikipedia:Manual of Style § Identity and Wikipedia:Gender-neutral language for further advice.

A Wikipedia article should not sound like a news article. Especially avoid bombastic wording, attempts at humor or cleverness, over-reliance on primary sources, editorializing, recentism, pull quotes, journalese, and headlinese.

Similarly, avoid persuasive writing, which has many of those faults and more of its own, most often various kinds of appeals to emotion and related fallacies. This style is used in press releases, advertising, editorial writing, activism, propaganda, proposals, formal debate, reviews, and much tabloid and sometimes investigative journalism. It is not Wikipedia's role to try to convince the reader of anything, only to provide the salient facts as best they can be determined, and the reliable sources for them.

Another error of writing approach is attempting to make bits of material "pop" (an undue weight problem), such as with excessive emphasis, over-capitalization, use of contractions, unnecessary acronyms and other abbreviations, the inclusion of hyperbolic adjectives and adverbs, or the use of unusual synonyms or loaded words. Present the sourced information without embellishment, agenda, fanfare, cleverness, or conversational tone.

An extreme example of hyperbole and emphatic language taken from Star Canopus diving accident as of 28 December 2019 (fixed in the next two revisions) read:

Miraculously both divers survived the 294-foot fall, but now they faced a harrowing predicament. ... Helplessly trapped, with nothing to keep them warm, ... all they could do was huddle together and pray that rescuers would find them in time. ... But time was not on their side.

This was fixed to:

Both divers survived the 294-foot fall.

See Wikipedia:Manual of Style/Words to watch for other examples. Avoid using words and phrases like terrible, rising star, curiously, championed the likes of, or on the other side of the pond, unless part of a quotation or stated as an external viewpoint.

Punctuation marks that appear in the article should be used only per generally accepted practice. Exclamation marks (!) should be used only if they occur in direct quotations.

As with exclamation marks, question marks (?) should also generally only be used if they occur in direct quotations; do not pose rhetorical questions for the reader.

For example, do not write:

There are many environmental concerns when it comes to industrial effluent. How can these be solved? Well, one solution involves ...

Rhetorical questions can occasionally be used, when appropriate, in the presentation of material, but only when the question is asked by the material under consideration, not being asked in Wikipedia's own voice.

For example:

One model of policy analysis is the "five-E approach", which consists of examining a policy in terms of:

Effectiveness

How well does it work (or how well will it be predicted to work)?

Efficiency

How much work does or will it entail? Are there significant costs associated with this solution, and are they worth it? ...^[1]

A related presentation problem is "info-dumping" by presenting information in the form of a long, bulleted list when it would be better as normal prose paragraphs. This is especially true when the items in the list are not of equal importance, or are not really comparable in some other way, and need context. Using explanatory prose also helps identify and remove trivia; if we cannot explain to readers why something is important, then it is not important.

Wikipedia is an international encyclopedia. People who read Wikipedia have different backgrounds, education and opinions. Make your article accessible and understandable for as many readers as possible. Assume readers are reading the article to learn. It is possible that the reader knows nothing about the subject, so the article needs to explain the subject fully.

Avoid using jargon whenever possible. Consider the reader. An article entitled "Use of chromatic scales in early Baroque music" is likely to be read by musicians, and technical details and terms are appropriate, linking to articles explaining the technical terms. On the other hand, an article entitled "Baroque music" is likely to be read by laypersons who want a brief and plainly written overview, with links to available detailed information. When jargon is used in an article, a brief explanation should be given within the article. Aim for a balance between comprehensibility and detail so that readers can gain information from the article.

Here are some thought experiments to help you test whether you are setting enough context:

• Does the article make sense if the reader gets to it as a random page?
• Imagine yourself as a layperson in another English-speaking country. Can you figure out what or who the article is about? Can you figure out whether a particular place or time is relevant?
• Can people tell what the article is about if the first page is printed out and passed around?
• Would a reader want to follow some of the links? Do sentences still make sense if they can't?

Remember that every Wikipedia article is tightly connected to a network of other topics. Establishing such connections via wikilink is a good way to establish context. Because Wikipedia is not a long, ordered sequence of carefully categorized articles like a paper encyclopedia, but a collection of randomly accessible, highly interlinked ones, each article should contain links to more general subjects that serve to categorize the article. When creating links, do not go overboard, and be careful to make your links relevant. It is not necessary to link the same term twelve times (although if it appears in the lead, then near the end, it might be a good idea to link it twice).

Avoid making your articles orphans. When you write a new article, make sure that one or more other pages link to it, to lessen the chances that your article will be orphaned through someone else's editing on those pages. Otherwise, when it falls off the bottom of the Recent Changes page, it will disappear into the Mariana Trench. There should always be an unbroken chain of links leading from the Main Page to every article in Wikipedia; following the path you would expect to use to find your article may give you some hints as to which articles should link to your article.

State facts that may be obvious to you, but are not necessarily obvious to the reader. Usually, such a statement will be in the first sentence or two of the article. For example, consider this sentence:

The Ford Thunderbird was conceived as a response to the Chevrolet Corvette and entered production for the 1955 model year.

Here no mention is made of the Ford Thunderbird's fundamental nature: it is an automobile. It assumes that the reader already knows this—an assumption that may not be correct, especially if the reader is not familiar with Ford or Chevrolet. Perhaps instead:

The Ford Thunderbird was a car manufactured in the United States by the Ford Motor Company.

However, there is no need to go overboard. There is no need to explain a common word like "car". Repetition is usually unnecessary, for example:

Shoichi Yokoi was conscripted into the Imperial Japanese Army in 1941.

conveys enough information (although it is not a good first sentence). However, the following is not only verbose but redundant:

Shoichi Yokoi was a Japanese soldier in Japan who was drafted into the Imperial Japanese Army in 1941.

As explained in more detail at Wikipedia:Lead section § Introductory text, all but the shortest articles should start with introductory text (the "lead"). The lead should establish significance, mention consequential or significant criticism or controversies, and be written in a way that makes readers want to know more. The appropriate length of the lead depends on the article, but is usually less than 400 words or so. The lead itself has no section heading.

Normally, the opening paragraph summarizes the most important points of the article. It should clearly explain the subject so that the reader is prepared for the greater level of detail that follows. If further introductory material is appropriate before the first section, it can be covered in subsequent paragraphs in the lead. Introductions to biographical articles commonly double as summaries, listing the best-known achievements of the subject. Because some readers will read only the opening of an article, the most vital information should be included.

The article should begin with a short declarative sentence, answering two questions for the nonspecialist reader: "What (or who) is the subject?" and "Why is this subject notable?"^[2]

• If possible, the page title should be the subject of the first sentence.^[3] In this case, it may appear in a slightly different form, should omit parenthetical disambiguators, and may include variations.^[4][5]
  • However, if the article title is merely descriptive—such as Electrical characteristics of dynamic loudspeakers—the title does not need to appear verbatim in the main text. Similarly, where the page title is of the type "List of ...", a clearer and more informative introduction to the list is better than verbatim repetition of the title. Furthermore, in biographical articles and articles about companies or organizations, the first sentence should generally start with a full form of name, regardless of article title.
• If its subject is amenable to definition, then the first sentence should give a concise definition: where possible, one that puts the article in context for the nonspecialist.^[6] Similarly, if the subject is a term of art, provide the context as early as possible.^[7]
• If the article is about a fictional character or place, make sure to say so.^[8]

• As a general rule, the first (and only the first) appearance of the page title should be in boldface as early as possible in the first sentence:

  An electron is a subatomic particle that carries a negative electric charge.

• However, if the title of a page is descriptive and does not appear verbatim in the main text, then it should not be in boldface. So, for example, Electrical characteristics of dynamic loudspeakers begins with:

  The chief electrical characteristic of a dynamic loudspeaker's driver is its electrical impedance as a function of frequency.

• If the subject of the page is normally italicized (for example, a work of art, literature, album, or ship) then its first mention should be both bold and italic text; if it is usually surrounded by quotation marks, the title should be bold but the quotation marks should not:

  Las Meninas (Spanish for The Maids of Honour) is a 1656 painting by Diego Velázquez, ...

  "Yesterday" is a pop song originally recorded by The Beatles for their 1965 album Help!

• If the subject of the page has a common abbreviation or more than one name, the abbreviation (in parentheses) and each additional name should be in boldface on its first appearance:

  Sodium hydroxide (NaOH), also known as lye, caustic soda and (incorrectly, according to IUPAC nomenclature) sodium hydrate, is ...

• Use as few links as possible before and in the bolded title. Thereafter, words used in a title may be linked to provide more detail:

  Arugam Bay is a bay situated on the Indian Ocean in the dry zone of Sri Lanka's southeast coast.

After the first sentence, proceed with a description. Remember, the basic significance of a topic may not be obvious to nonspecialist readers, even if they understand the basic characterization or definition. Tell them. For instance:

Peer review, known as refereeing in some academic fields, is a scholarly process used in the publication of manuscripts and in the awarding of money for research. Publishers and agencies use peer review to select and to screen submissions. At the same time, the process assists authors in meeting the standards of their discipline. Publications and awards that have not undergone peer review are liable to be regarded with suspicion by scholars and professionals in many fields.

If the article is long enough for the lead section to contain several paragraphs, then the first paragraph should be short and to the point, with a clear explanation of what the subject of the page is. The following paragraphs should give a summary of the article. They should provide an overview of the main points the article will make, summarizing the primary reasons for the subject matter being interesting or notable, including its more important controversies, if there are any.

The sequence in which you edit should usually be: first change the body, then update the lead to summarize the body. Several editors might add or improve some information in the body of the article, and then another editor might update the lead once the new information has stabilized. Don't try to update the lead first, hoping to provide direction for future changes to the body. There are three reasons why editing the body first and then making the lead reflect it leads to improvement of articles.

First, it keeps the lead in sync with the body. The lead, being a summary of the article, promises that the body will deliver fuller treatment of each point. Generally, wiki pages are imperfect at all times, but they should be complete, useful articles at all times. They should not contain "under construction" sections or refer to features and information that editors hope they will contain in the future. It's much worse for the lead to promise information that the body does not deliver than for the body to deliver information that the lead does not promise.

Second, good ways to summarize material usually only become clear after that material has been written. If you add a new point to the lead before it's covered in the body, you only think you know what the body will eventually contain. When the material is actually covered in the body, and checked and improved, usually by multiple editors, then you know. (If having a rough, tentative summary helps you write the body, keep your own private summary, either on your computer or in your User space.)

Third, on contentious pages, people often get into edit wars over the lead because the lead is the most prominent part of the article. It's much harder to argue constructively over high-level statements when you don't share common understanding of the lower-level information that they summarize. Space is scarce in the lead, so people are tempted to cram too much into one sentence, or pile on lots of references, in order to fully state and prove their case—resulting in an unreadable lead. In the body, you have all the space you need to cover subtleties and to cover opposing ideas fairly and in depth, separately, one at a time. Once the opposing ideas have been shaken out and covered well in the body, editing the lead without warring often becomes much easier. Instead of arguing about what is true or what all the competing sources say, now you are just arguing over whether the lead fairly summarizes what's currently in the body.

It is fine to include foreign terms as extra information, but avoid writing articles that can only be understood if the reader understands the foreign terms. Such words are equivalent to jargon, which should be explained somehow. In the English-language Wikipedia, the English form does not always have to come first: sometimes the non-English word is better as the main text, with the English in parentheses or set off by commas after it, and sometimes not. For example, see Perestroika.

Non-English words in the English-language Wikipedia should be written in italics, with the exception of non-Latin scripts such as Greek, Cyrillic, and Chinese. Non-English words should be used as titles for entries only as a last resort. Again, see Perestroika.

English title terms taken from a language that does not use the Roman alphabet can include the native spelling in parentheses. See, for example, I Ching (simplified Chinese: 易经; traditional Chinese: 易經; pinyin: Yìjīng) or Sophocles (Ancient Greek: Σοφοκλῆς). The native spelling is useful for precisely identifying foreign words, since transliterations may be inaccurate or ambiguous. Foreign terms within the article body do not need native spellings if they can be specified as title terms in separate articles; just link to the appropriate article on first occurrence.

If possible, avoid presenting information with color only within the article's text and in tables.

Color should only be used sparingly, as a secondary visual aid. Computers and browsers vary, and you cannot know how much color, if any, is visible on the recipient's machine. Wikipedia is international: colors have different meaning in different cultures. Too many colors on one page look cluttered and unencyclopedic. Specifically, use the color red only for alerts and warnings.

Awareness of color should be allowed for low-vision viewers: poor lighting, color blindness, screen reader software, dark or overbright screens, monochrome screens, and the wrong contrast/color settings on the display screen.

Articles should use only necessary words. This does not mean using fewer words is always better; rather, when considering equivalent expressions, choose the more concise.

Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all his sentences short, or that he avoid all detail and treat his subjects only in outline, but that every word tell.

Reduce sentences to the essentials. Wordiness does not add credibility to Wikipedia articles. Avoid circumlocutions like "due to the fact that" in place of "because", or "at the present time" for "currently". Ongoing events should be qualified with "as of 2026".

Conciseness alone does not justify removing information from an article.

When the principle of least astonishment is successfully employed, information is understood by the reader without struggle. The average reader should not be shocked, surprised, or confused by what they read. Do not use provocative language. Instead, offer information gently. Use consistent vocabulary in parts that are technical and difficult. To work out which parts of the sentence are going to be difficult for the reader, try to put yourself in the position of a reader hitherto uninformed on the subject.

You should plan your page structure and links so that everything appears reasonable and makes sense. A link should not take readers to somewhere other than where they thought it would go. Avoid Easter-egg links, which require the reader to open them before understanding what's going on. Instead, use a short phrase or a few words to describe what the link will refer to once it's opened.

Similarly, make sure that concepts being used as the basis for further discussion have already been defined or linked to a proper article. Explain causes before consequences and make sure your logical sequence is clear and sound, especially to the layperson. Ensure that redirects and hatnotes that are likely to be useful are in place.

We cannot control all astonishment – the point of an encyclopedia is to learn things, after all. But limiting the surprises our readers find within our articles' text will encourage rather than frustrate our readers.

Phrases such as refers to, is the name of, describes, or is a term for are sometimes used inappropriately in the first sentence of Wikipedia articles.

For most articles, the introduction is using a term, rather than mentioning it. This is known as the use–mention distinction.

For example, the article Computer architecture once began with the sentence, "Computer architecture refers to the theory behind the design of a computer." That is not true: Computer architecture is the theory. The words "computer architecture" refer to the theory, but the article is not about the words; it is about the theory. Thus it is better to say, "Computer architecture is the theory behind the design of a computer."

To speak easily of the scope of a hyponym without confusing the term for the thing, one can simply say that "[hyponym] is any of various [hypernym]" or "any of a class of [hypernym] with trait X", such as "A pine is any conifer in the genus Pinus of the family Pinaceae" (not "Pine refers to any tree in the genus Pinus of the family Pinaceae").

For some controversial topics, using a term in wikivoice might compromise neutrality, as in race card and chick lit—two concepts that are discussed, but not broadly accepted, in reliable sources. In such cases, it may be appropriate to use the "refers to" formulation to introduce a topic without concealing legitimate controversy.

Disambiguation pages mention the term, so in such cases it is correct to write "Great Schism may refer to either of two schisms in the history of Christianity: ...". However, a content article should read "There have been two Great Schisms in the history of Christianity".

Similarly, use of the term is when is discouraged in the first sentence, as it may be imprecise, produce vague or circular definitions, or define a term using a time clause when time is not central to the definition. Instead, use a strong copula like is, followed by a noun phrase.

For example, the article Nuchal cord once began with the sentence, "A nuchal cord is when the umbilical cord becomes wrapped around the fetus's neck." However, timing has nothing to do with the definition. It is better to say, "A nuchal cord is a condition in which the umbilical cord becomes wrapped around the fetus's neck."

Write material that is true: check your facts. Do not write material that is false. This might require that you verify your alleged facts.

This is a crucial part of citing good sources: even if you think you know something, you have to provide references anyway to prove to the reader that the fact is true. Material that seems to naturally stem from sourced claims might not have been actually claimed. In searching for good references to cite, you might even learn something new.

Be careful about deleting material that may be factual. If you are inclined to delete something from an entry, first consider checking whether it is true. If material is apparently factual, in other words substantiated and cited, be extra careful about deleting. An encyclopedia is a collection of facts. If another editor provided a fact, there was probably a reason for it that should not be overlooked. Therefore, consider each fact provided as potentially precious. Is the context or overall presentation the issue? If the fact does not belong in one particular article, maybe it belongs in another.

Examine entries you have worked on subsequent to revision by others. Have facts been omitted or deleted? It may be the case that you failed to provide sufficient substantiation for the facts, or that the facts you incorporated may need a clearer relationship to the entry. Protect your facts, but also be sure that they are presented meaningfully.

The advice about factual articles also applies to articles on fiction subjects. Further considerations apply when writing about fictional topics because they are inherently not real. It is important to keep these articles verifiable and encyclopedic.

If you add fictional information, clearly distinguish fact and fiction. As with normal articles, establish context so that a reader unfamiliar with the subject can get an idea about the article's meaning without having to check several links. Instead of writing:

Trillian is Arthur Dent's girlfriend. She was taken away from Earth by Zaphod when he met her at a party. She meets Dent while travelling with Zaphod.

write:

Trillian is a fictional character from Douglas Adams's radio, book and film series The Hitchhiker's Guide to the Galaxy. In the first book, Trillian is introduced to the main character Arthur Dent on a spaceship. In her backstory, she was taken away from Earth when the space alien Zaphod Beeblebrox met her at a party.

Works of fiction are generally considered to "come alive" for their audience. They therefore exist in a kind of perpetual present, regardless of when the fictional action is supposed to take place relative to the reader's "now". Thus, generally you should write about fiction using the historical present tense, not the past tense. (See WP:Manual of Style § Verb tense and WP:Manual of Style/Writing about fiction § Contextual presentation.) Examples:

Homer presents, Achilles rages, Andromache laments, Priam pleads.

Holden Caulfield has a certain disdain for what he sees as 'phony'.

Friends is an American sitcom that was aired on NBC.

Conversely, discussion of history is usually written in the past tense and thus "fictional history" may be presented in that way as well.

Chroniclers claimed that Thalestris, queen of the Amazons, seduced Alexander the Great.

Articles about fictional topics should not read like book reports; instead, they should explain the topic's significance to the work. After reading the article, the reader should be able to understand why a character, place, or event was included in the fictional work.

Editors are generally discouraged from adding fictional information from sources that cannot be verified or are limited to a very small number of readers, such as fan fiction and online role-playing games. In the latter case, if you absolutely have to write about the subject, please be especially careful to cite your sources.

If the subject, say a character in a television show, is too limited to be given a full article, then integrate information about that character into a larger article. It is better to write a larger article about the television show or a fictional universe itself than to create all sorts of stubs about its characters that nobody can find.

The most readable articles contain no irrelevant (nor only loosely relevant) information. While writing an article, you might find yourself digressing into a side subject. If you are wandering off-topic, consider placing the additional information into a different article, where it will fit more closely with that topic. If you provide a link to the other article, readers who are interested in the side topic have the option of digging into it, but readers who are not interested will not be distracted by it.

Pay attention to spelling, particularly of new page names. Articles with good spelling and proper grammar can help encourage further contributions of well-formed content. Proper spelling of an article name will also make it easier for other authors to link their articles to your article. Sloppiness begets sloppiness, so always do your best.

• Browsers have the native ability to highlight misspelled words in text boxes.
• Use free online dictionaries like Ask Oxford, Dictionary.com, Onelook.com, Google Define and a spell checker such as SpellCheck.net, GingerSoftware, or your browser's built-in spell checker. See Wikipedia:Typo Team for tips on how to use these resources.
• Articles may also be spell-checked in a word processor before being saved. A free word processor may be obtained from OpenOffice.org or LibreOffice.org.
• A "draft" message on certain free email websites, such as Gmail, can also provide spell-check. This might be convenient, especially regarding email websites with which you are already familiar and use often.

Avoid peacock terms that show off the subject of the article without containing any real information. Similarly, avoid weasel words that offer an opinion without really backing it up, and which are really used to express a non-neutral point of view.

Believe in your subject. Let the facts speak for themselves. If your ice hockey player, canton, or species of beetle is worth the reader's time, it will come out through the facts. However, in some cases (for example, history of graphic design) using superlative adjectives (in the "... one of the most important figures in the history of ..." format) in the description may help readers with no previous knowledge about the subject to learn about the importance or generally perceived status of the subject discussed. Note that to use this type of superlative adjective format, the most reputable experts in the relevant field must support the claim.

Avoid blanket terms unless you have verified them. For example, this article states that of the 18 Montgomery Counties in the United States, most are named after Richard Montgomery. This is a blanket statement. It may very well be true, but is it reliable? In this instance, the editor had done the research to verify this. Without the research, the statement should not be made. It is always a good idea to describe the research done and sign it on the article's talk page.

If you wish to, or must refer to an opinion, first make sure someone who holds some standing in that subject gives it. A view on former American President Gerald Ford from Henry Kissinger is more interesting for the reader than one from your teacher from school. Then say who holds the opinion being given, preferably with a source or a quote for it. Compare the following:

Some critics of George W. Bush have said he has low intelligence.

Author Michael Moore in his book Stupid White Men ...and Other Sorry Excuses for the State of the Nation! wrote an open letter to George Bush. In it, he asked, "George, are you able to read and write on an adult level?"

Sometimes the way around using these terms is to replace the statements with the facts that back them up. Instead of:

The Yankees are one of the greatest baseball teams in history.

Write:

The New York Yankees have won 27 World Series championships—almost three times as many as any other team.

By sticking to concrete and factual information, we can avoid the need to give any opinion at all. Doing so also makes for writing that is much more interesting, for example:

William Peckenridge, eighth Duke of Omnium (1642? – May 8, 1691) is widely considered to be one of the most important men to carry that title.

William Peckenridge, eighth Duke of Omnium (1642? – May 8, 1691) was a personal counselor to King James I, general in the Wars of the Roses, a chemist, bandleader, and the director of the secret society known as The League of Extraordinary Gentlemen. He expanded the title of Omnium to include protectorship of Guiana and right of revocation for civil-service appointments in India.

Show, don't tell. The first example simply tells the reader that William Peckenridge was important. The second example shows the reader why he was important.

When repeating established views, it may be easier to simply state: "Before Nicolaus Copernicus, most people thought the sun revolved round the earth", rather than sacrifice clarity with details and sources, particularly if the statement forms only a small part of your article. However, in general, everything should be sourced, whether within the text, with a footnote, or with a general reference.

Make omissions explicit when creating or editing an article. When writing an article, always aim for completeness. If for some reason you cannot cover a point that should be explained, make that omission explicit. You can do this either by leaving a note on the discussion page or by leaving HTML comments within the text and adding a notice to the bottom about the omissions. This has two purposes: it entices others to contribute, and it alerts non-experts that the article they are reading does not yet give the full story.

That's why Wikipedia is a collaborative encyclopedia—we work together to achieve what we could not achieve individually. Every aspect that you cover means less work for someone else, plus you may cover something that someone else may not think of but which is nevertheless important to the subject. Add {{To do}} to the top of the talk page of articles for which you can establish some goals, priorities or things to do.

Honorifics

Do not use honorifics or titles, such as Mr, Ms, Rev, Doctor, Professor, etc. See Wikipedia:Naming conventions (royalty and nobility) and Wikipedia:Manual of Style/Biography

Inappropriate subjects

If you are trying to dress up something that doesn't belong in Wikipedia—your band, your Web site, your company's product—think twice about it. Wikipedia is not an advertising medium or home page service. Wikipedians are pretty clever, and if an article is really just personal gratification or blatant advertising, it's not going to last long—no matter how "important" you say the subject is.

Integrate changes

When you make a change to some text, rather than appending the new text you would like to see included at the bottom of the page, if you feel so motivated, please place and edit your comments so that they flow seamlessly with the present text. Wikipedia articles should not end up being a series of disjointed comments about a subject, but unified, seamless, and ever-expanding expositions of the subject.

Avoiding common mistakes

It is easy to commit a Wikipedia faux pas. That is OK—everybody does it! Nevertheless, here are a few you might try to avoid.

Make a personal copy

Suppose you get into an edit war. Or worse, a revert war. Therefore, you try to stay cool. This is good. Congratulations! However, what would be great is if you could carry on working on the article, even though there is an edit war going on, and even though the version on the top is the evil one favored by the other side in the dispute.

So, make a temporary personal copy as a subpage of your user page. Just start a new page at Special:MyPage/Article name (it can be renamed in the URL address to start a page with a different article name), and copy and paste the wiki-source in there. Then you can carry on improving the article at your own pace! If you like, drop a note on the appropriate talk page to let people know what you are doing.

Some time later, at your leisure, once the fuss has died down, merge your improvements back in to the article proper. Maybe the other person has left Wikipedia, finding it not to their taste. Maybe they have gone on to other projects. Maybe they have changed their mind. Maybe someone else has made similar edits anyway (although they may not be as good as yours, as you have had more time to consider the matter). Alternative versions of pages should be deleted once you are finished with them.
