Alternative spelling

The first portion nama is from 生 (nama). This usually has a sense of raw but also has overtones of unprocessed, unready and thus some semantic overlap with, and is cognate with, 鈍る (namaru, “to become dull, especially due to lack of proper tempering”).

The second portion kura is of uncertain derivation.

The term is first cited to 1711.^[1]

IPA^(key): [na̠ma̠kɯ̟ɾa̠]

(uncommon) dull of edge, unable to cut well
(uncommon) dull of mind, lazy, insipid

Noun

鈍(なまくら) • (namakura)

Derived terms

鈍(なまくら)刀(がたな) (namakura-gatana, “a dull sword”)
鈍(なまくら)武(ぶ)士(し) (namakura bushi, “a warrior with a dull sword; a warrior with no ambition”)
鈍(なまくら)物(もの) (namakuramono, “a dull blade”)

Etymology 3

Grade: S

Shift in usage, repurposing the stem of 形容詞 (keiyōshi, “-i adjective”) 鈍い (noroi, “slow of thought or action”) as a 形容動詞 (keiyō dōshi, “-na adjective”).^[3]^[4]

First cited to a work from 1891.^[4]
