用法說明
How is "Definitely" different from similar structures?What usage mistakes are common with "Definitely"?
definitely 與助動詞、動詞形式的搭配
- definitely 通常置於主要動詞之前、助動詞（如 will, would, can, should）之後。
- 在否定句中，definitely 通常放在助動詞與否定詞 not 之間，例如 "will definitely not"。
- 它修飾的是整個動詞片語，強調說話者對所述動作或狀態的確定性。
- 它後面直接接動詞原形（如 definitely go），而非不定詞 "to"（不正確：definitely to go）或動名詞 "-ing" 形式（不正確：definitely going，除非是進行式的一部分）。
對比例句： EN: She will definitely call you tomorrow. 翻譯: 她明天肯定會打電話給你。
EN:She definitely will not call you tomorrow.
翻譯:她明天肯定不會打電話給你。
總結建議
使用 definitely 時，請將其置於助動詞之後、主要動詞之前，並避免在其後直接使用 "to" 或 "-ing"。

常見錯誤
What are common mistakes with "Definitely"?Which "Definitely" sentences look correct but are wrong?
×definately
✓definitely
這是一個常見的拼寫錯誤。正確拼法是 'definitely'，其中包含 'ite' 音節，而不是 'ate'。
×definatly
✓definitely
漏掉了 'e' 和 'i'。正確拼法必須包含所有音節：def-i-nite-ly。
×I definitely will go.
✓I will definitely go.
在簡單未來式 (will + 動詞) 中，副詞 'definitely' 通常放在 'will' 和主要動詞之間。
×I definitely don't know.
✓I definitely don't know. / I don't know for sure.
'Definitely' 與否定句連用時，語氣非常強烈，表示「絕對不」。在許多語境中，使用 'for sure' 或 'certainly' 可能更自然。原句文法正確，但語氣可能過強，是語用上的常見錯誤。
×This is the definitely answer.
✓This is the definitive answer.
'Definitely' 是副詞，用來修飾動詞、形容詞或其他副詞，表示「肯定地」。'Definitive' 是形容詞，意思是「確定的、決定性的、最權威的」。這裡需要形容詞來修飾名詞 'answer'。
×Yes, definitely yes!
✓Definitely! / Yes, definitely!
在口語中，'definitely' 本身就已經表達了強烈的肯定，加上另一個 'yes' 顯得多餘且不自然。
