caudal fin; tail fin
Refers to the tail fin of a fish. The reading おひれ is sometimes used, but おびれ is standard.
The goldfish's tail fin is beautiful.
This fish has a large tail fin.
Common mixed kanji-kana spelling; the kanji 尾 means 'tail' and びれ is the kana for 'fin'.
Full kanji spelling; 鰭 is a non-jōyō kanji, so this form is less common in everyday writing.
Compound of 尾 (o, 'tail') + ひれ (hire, 'fin'). The initial 'h' of ひれ voices to 'b' due to rendaku, giving おびれ.
