螺子

Japanese

Etymology 1

Kanji in this term
螺	子
Jinmeiyō	し > じ Grade: 1
irregular	on’yomi

/nedi/ → /ned͡ʑi/

The 連用形 (ren'yōkei, “stem or continuative form”) of 上一段活用 (kami ichidan katsuyō, “upper monograde conjugation”) verb 捩じる (nejiru, “to screw, twist”). Alteratively, from the stem form of classical 上二段活用 (kami nidan katsuyō, “upper bigrade conjugation”) verb 捩づ (nedzu → nezu) of the same meaning.

The use of 螺 (“spiral-shelled shellfish”) is an example of jukujikun (熟字訓) from the spiral shape of the screw. The use of 子 (shi, diminutive suffix) is an example of phonetic ateji (当て字), despite the historical spelling.
