常見錯誤
What are common mistakes with "Decisive"?Which "Decisive" sentences look correct but are wrong?
×He is a very decided person.
✓He is a very decisive person.
雖然 'decided' 也是形容詞，但 'decisive' 更常用來形容人的性格特質，表示「果斷的、有決斷力的」。'Decided' 更常指「明確的、明顯的」，例如 a decided advantage（明顯的優勢）。
×The goal was very decisive for winning the match.
✓The goal was decisive in winning the match.
描述某事物是「決定性的因素」時，慣用介系詞是 'in' 或 'for'，但搭配稍有不同。'Decisive in + V-ing / noun' 表示在...過程中起決定作用；'decisive for + noun' 表示對...而言是決定性的。原句語意用 'in' 更自然。
×We should make a decisive decision quickly.
✓We should make a decision quickly.
'decisive' 和 'decision' 語義重複，因為 decision 本身就涉及做決定。如果要強調決定是「果斷的」或「決定性的」，可以說 'make a quick decision' 或 'make a firm decision'，或者用 'We should be decisive and make a decision quickly.'
×This is a decisive important moment.
✓This is a decisive moment.
'decisive' 本身已包含「關鍵的、重要的」意思，不需要再與 'important' 並列使用，否則顯得冗餘。直接用 'decisive' 即可。
×She spoke with a decisive voice.
✓She spoke in a decisive tone. / She spoke decisively.
描述說話的「語氣果斷」，更地道的說法是 'in a decisive tone' 或使用副詞 'decisively'。'with a decisive voice' 聽起來不自然，像是直譯。
×The judge gave a decisive judgement.
✓The judge gave a decisive ruling. / The judge's judgement was decisive.
雖然 'judgement' 和 'ruling' 意思相近，但與 'decisive' 搭配時，'decisive ruling' 或 'decisive verdict' 是更常見的法律用語搭配。也可以換個結構，將 'decisive' 作為主詞補語。
