Choosing the right word

  • 灼熱しゃくねつCommon
    no-adjective, suru verb, intransitive verbIntense, burning passion, as in burning love or a passionate debate. It is vivid and forceful, suiting dramatic or literary descriptions of white-hot emotion rather than casual conversation.
  • コアCommon
    na-adjectiveHere it means 'passionate' in the colloquial, all-out hardcore sense, as of devoted fans or fans' enthusiasm. It is a borrowed word, so reserve it for casual speech, not for describing feelings in neutral or formal prose.
