Usage

A more formal and literary variant of なら (if). Attaches to the plain form of verbs and adjectives, and to nouns directly or with である for extra formality. Common in written Japanese, speeches, and formal conversation. In everyday speech, なら is preferred.

Common patterns

  • それならば (if that is the case — common sentence opener)
  • するならば (if one does ~)
  • であるならば (if it is ~ — formal)
