用法說明
How is "Firstly" different from similar structures?What usage mistakes are common with "Firstly"?
firstly vs. first
- firstly 是正式的副詞，主要用於列舉觀點或步驟，尤其是在演講或寫作中。
- first 則更為通用，既可作副詞（與 firstly 同義），也可作形容詞或名詞。在非正式口語中，許多人直接用 first 來開始列舉。
- 在列舉多個項目時，傳統上建議使用 firstly, secondly, thirdly... 的序列以保持一致性，但現代用法也普遍接受 first, second, third...。 EN: Firstly, we need to define our objectives. Secondly, we will allocate resources. 翻譯: 首先，我們需要定義目標。其次，我們將分配資源。
EN:First, let me thank you all for coming. Second, I'll outline the agenda.
翻譯:首先，讓我感謝各位的到來。其次，我將概述議程。

常見錯誤
What are common mistakes with "Firstly"?Which "Firstly" sentences look correct but are wrong?
×Firstly, I want to say thank you.
✓First, I want to say thank you.
在非正式或簡潔的口語中，通常使用 "first" 而非 "firstly" 來開始列舉。"Firstly" 在正式寫作中更常見，但口語中常被 "first" 取代。
×The reasons are firstly, it's expensive, and second, it's time-consuming.
✓The reasons are, first, it's expensive, and second, it's time-consuming.
在 "The reasons are" 這類主詞補語結構後，應使用 "first", "second" 等，而非 "firstly", "secondly"。"Firstly" 通常用於引導獨立副詞子句。
×Firstly of all, I'd like to welcome everyone.
✓First of all, I'd like to welcome everyone.
"First of all" 是一個固定片語，不能將 "first" 替換為 "firstly"。
×We need to do it firstly.
✓We need to do it first.
當表示「最先做某事」的順序時，應使用形容詞或副詞 "first"，而非 "firstly"。"Firstly" 主要用於正式列舉論點或步驟。
×Firstly, the budget. Secondly, the schedule. Thirdly, the team.
✓First, the budget. Second, the schedule. Third, the team.
在簡潔的列表或提綱式寫作中（如簡報重點），通常使用 "First,", "Second," 等，而非 "Firstly,", "Secondly,"。後者更適合完整的句子和段落。
×I have two points. Firstly is about cost.
✓I have two points. The first is about cost.
"Firstly" 是副詞，不能作為主詞。當需要名詞性主詞時，應使用 "The first" 或 "First"（作為名詞）。
