How to say "crunch" in Japanese

Choosing the right word
  • 天王山てんのうざんCommon
    nounThe figurative sense only: a decisive, make-or-break point in a contest, negotiation or project — what English calls crunch time. It never describes actual biting or crunching sounds.
  • 噛み砕くかみくだく
    godan verb, transitive verbThe physical sense: to crunch or masticate — to bite and break something down with the teeth. Use it when 'crunch' is the chewing action itself, as with crisp or hard food.
  • nounA loanword taken directly from English, and a less common one. Use it where the borrowed term itself fits — the crunchy texture of a snack, for example — rather than for the act of chewing.
  • interjection, adverb (with と)An onomatopoeia for a loud, harsh impact — a crash, smash or bang. Its 'crunch' is the sound of something hard breaking or colliding, not of chewing and not of a critical moment.
  • 噛みしだくかみしだく
    godan verb, transitive verbAlso the physical sense: to crush something with the teeth, crunching it as you chew. It overlaps closely with 噛み砕く and is itself less common; either verb serves for the action of chewing.

Use 天王山 for the figurative crunch of a decisive moment, 「噛み砕く」 or 「噛みしだく」 for the physical chewing action, 「ガシャン」 for a loud crunching crash, and 「クランチ」 where the English loanword itself is wanted.
