COMMON COLLOCATIONS:

  • いかなる場合(ばあい)も — under any circumstances
  • いかなる理由(りゆう)であっても — for whatever reason
  • いかなる困難(こんなん)にも — against any difficulty
  • いかなる状況(じょうきょう)でも — in any situation

USAGE:
Appears frequently in legal documents, formal speeches, rules and regulations, and literary prose. In sense 2, often paired with も to create a 'no matter what' construction (いかなる〜も). Too formal for casual conversation — use どんな instead in everyday speech.

SIMILAR WORDS:

  • どんな — what kind of; any (casual everyday equivalent)
  • いかに — how; to what extent (adverb, not prenominal)
  • どのような — what kind of (polite but less formal than いかなる)
