えら

えら
noun
gills (of a fish)
1. gills
The respiratory organs on the sides of fish (and some other aquatic animals) that allow them to extract oxygen from water.
(さかな)はえらで呼吸(こきゅう)する。
Fish breathe through their gills.
(あたら)しい(さかな)はえらが(あか)い。
A fresh fish has red gills.
調理(ちょうり)する(まえ)に、(さかな)のえらと内臓(ないぞう)をきれいに()(のぞ)いた。
Before cooking, I cleanly removed the fish's gills and innards.

Written in kanji as (えら), but the kana form is more common in everyday writing. Used both literally for fish anatomy and metaphorically.

COMMON COLLOCATIONS:

  • えらで呼吸(こきゅう)する: to breathe through gills
  • えらを()る: to remove the gills (in fish preparation)
  • (あか)いえら: red gills (a sign of freshness)

FIGURATIVE USE:
えらが()る can describe a person with a wide jaw or angular jawline (literally "the jaw/gill juts out"). In this use えら refers to the angle of the jaw, not the fish organ.
