水鶏

/kufina/ → /kuwina/ → /kuina/

First attested in the Edo period.

Derivation uncertain. Thought to be a shift from a compound of 食い (kui, stem form of verb 食う (kuu), “to put in one's mouth, eat”) +‎ 鳴く (naku, “to call, said of a bird”). (Can this⁽⁺⁾ etymology be sourced?)

The kanji spelling means literally "water chicken".
