くちばし

くちばし
noun
beak; bill (of a bird)

くちばし comes from (くち) (mouth) + (はし) (edge/tip). Usually written in kana; the kanji (くちばし) is rarely used.

COMMON COLLOCATIONS:

  • くちばしが(なが)い: has a long beak
  • くちばしで()く: to peck with its beak
  • くちばしで(えさ)(はこ)ぶ: to carry food in its beak

IDIOM:

くちばしを(はさ)む means to butt into someone else's conversation or business. Equivalent to the English "to stick one's nose in."

  • くちばしを(はさ)むな: Don't butt in!

NOTE:
The shape and size of a bird's beak is a key topic in nature documentaries and science education in Japan, so this word appears often in those contexts.
