  • 披露ひろうCommon

  • デモJLPT N3approx.Common

    デモに参加さんかしようと思おもう。↗
    I'm going to join a demonstration.
  • 実証じっしょうCommon
    suru verb, no-adjective, transitive verb, intransitive verbDemonstration as substantiation: showing that something is true with actual evidence, so it also serves for verification and actual proof.
    この理論りろんの根拠こんきょをこれから実証じっしょうしよう。↗
    I am going to substantiate this theory.

English 'demonstration' splits by sense: use 「デモ」 for street protests, 証明 for logical or mathematical proof, 実証 for empirical substantiation, 発揮 for showing one's abilities, and 披露 for formally presenting something.
