螺子

Japanese

Etymology 1
Kanji in this term
螺 子
Jinmeiyō し > じ
Grade: 1
Irregular

/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”).[1] 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.[2]

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, diminuative suffix) is an example of phonetic ateji (当て字), despite the historical spelling.
