Macron below - Wikipedia

From Wikipedia, the free encyclopedia

(Redirected from Combining macron below)

◌̱
Macron below
U+0331 ◌̱ COMBINING MACRON BELOW

A̱a̱ḆḇC̱c̱

Macron below is a combining diacritical mark that is used in various orthographies.^[1]

A non-combining form is U+02CD ˍ MODIFIER LETTER LOW MACRON. It is not to be confused with U+0320 ◌̠ COMBINING MINUS SIGN BELOW, U+0332 ◌̲ COMBINING LOW LINE and U+005F _ LOW LINE. The difference between "macron below" and "low line" is that the latter results in an unbroken underline when it is run together: compare a̱ḇc̱ and a̲b̲c̲ (only the latter should look like abc).^[2]

Precomposed characters

Various precomposed letters with a macron below are defined in Unicode:

upper case			lower case			notes
letter	Unicode	HTML	letter	Unicode	HTML	notes
Ḇ	U+1E06	Ḇ	ḇ	U+1E07	ḇ	Used in the transliteration of Biblical Hebrew into the Roman alphabet to show the fricative value of the letter beth (ב) representing [v], or perhaps [β].
Ḏ	U+1E0E	Ḏ	ḏ	U+1E0F	ḏ	Used in the transliteration of Biblical Hebrew, Syriac and Arabic into the Roman alphabet to show the fricative value of the letter dalet (ד), [ð], and in the romanization of Pashto, it is used sometimes to represent retroflex D. In Dravidian languages' transcription it represents an alveolar /d/.
			ẖ	U+1E96	ẖ	Sometimes used for Arabic خ ẖāʼ, Hebrew Heth (letter), Egyptian 𓄡. There is no precomposed upper case equivalent of ẖ so it uses a combining macron below instead: H̱.
Ḵ	U+1E34	Ḵ	ḵ	U+1E35	ḵ	Used in the transliteration of Biblical Hebrew into the Roman alphabet to show the fricative value of the letter kaph (כ) representing [x]. Used in Tlingit and Haida (among other Pacific Northwest languages) for the voiceless uvular stop [q]. Close to Korean ㄲ kk; closest English "shocking" Used optionally in the K-dialect of Māori in the South Island of New Zealand, where an original ng has merged with k. The ḵ indicates that it corresponds to ng in other dialects. There is no difference in pronunciation between ḵ and k.
Ḻ	U+1E3A	Ḻ	ḻ	U+1E3B	ḻ	One possible transliteration of the Dravidian retroflex approximant /ɻ/ as in Tamil letter ழ. Ḻ is used in the Seri language to represent [l], like English l, while unmodified "l" represents [ɬ], like Welsh ll. It is also used in the proposed Unified Alphabet for Mapudungun.
Ṉ	U+1E48	Ṉ	ṉ	U+1E49	ṉ	Used in Pitjantjatjara to represent [ɳ], and in Saanich to represent both plain and glottalized [ɴ]. In the romanization of Pashto, it is used sometimes to represent retroflex N. In Dravidian languages' transcription it represents an alveolar /n/.
Ṟ	U+1E5E	Ṟ	ṟ	U+1E5F	ṟ	Used in Pitjantjatjara to represent [ɻ], and sometimes in the romanization of Pashto to represent the retroflex R. In Dravidian languages' transcription it represents an alveolar trill /r/.
Ṯ	U+1E6E	Ṯ	ṯ	U+1E6F	ṯ	Used in the proposed Unified Alphabet for Mapudungun language representing [t̪]. In the romanization of Pashto, it is used sometimes to represent retroflex T. In Dravidian languages' transcription it represents an alveolar /t/. In the romanization of Arabic this letter is used to transcribe the letter Ṯāʾ.
Ẕ	U+1E94	Ẕ	ẕ	U+1E95	ẕ	Used in the 1953 Hebrew Academy Romanization of Hebrew to represent tsade (צ).
₫	U+20AB	₫				Vietnamese đồng.

Note that the Unicode character names of precomposed characters whose decompositions contain U+0331 ◌̱ COMBINING MACRON BELOW use "WITH LINE BELOW" rather than "WITH MACRON BELOW". Thus, U+1E07 ḇ LATIN SMALL LETTER B WITH LINE BELOW decomposes to U+0062 b LATIN SMALL LETTER B and U+0331 ◌̱ COMBINING MACRON BELOW.^[3]

The Vietnamese đồng currency sign resembles a lower case d with a stroke and macron below: U+20AB ₫ DONG SIGN but is neither a letter nor decomposable.^[4]

Spacing Overscores and Underscores. U+203E OVERLINE is the above-the-line counterpart to U+005F low line. It is a spacing character, not to be confused with U+0305 COMBINING OVERLINE. As with all overscores and underscores, a sequence of these characters should connect in an unbroken line. The overscoring characters also must be distinguished from U+0304 COMBINING MACRON, which does not connect horizontally in this way.
