assertiveness
自己主張
解説 Definition
積極性とは、自分の意見や要望をはっきり主張し、相手の権利を尊重しながらも自分の立場を守る態度です。受動的ではなく、能動的に行動する姿勢を表します。
Assertiveness is the quality of expressing your thoughts, needs, or opinions clearly and confidently. It is usually seen as a positive communication skill, but it should be balanced so it does not become aggression.
覚え方のコツ Memory Tip
まず assert を「はっきり言う・主張する」と押さえると覚えやすいです。I think so. を遠慮なく言える感じで、aggressive のような強引さとは違い、相手を押しのけないのがポイント。assertive communication, be assertive in meetings などの場面でよく出ます。語尾 -ness は「性質」を表すので、assertive → assertiveness で「自分の考えを適切に伝える性質」とつなげると定着します。
Build it from assert + -ive + -ness. The word suggests speaking up and stepping forward, not staying passive. Remember the contrast: assertiveness is confident and active, but not the same as aggressiveness.
