用來引出具體的例子，後面接名詞或名詞片語（若要接動作，用動名詞 V-ing 作名詞）。通常置於名詞之後；作非必要補充時，前面常以逗號隔開（如：Some apps, such as Instagram, ...）。若為必要分類可不加逗號（如：Foods such as tofu ...）。不可單獨放在句首當「例如」使用；句首請改用 For example 或 For instance。避免與 etc. 同時使用（語意重複）。與 like 不同：like 表「像、類似」，未必是確切例子；正式寫作列舉具體例子時，優先用 such as。

常見錯誤
✗
Such as apples and bananas are healthy.
✓
Fruits, such as apples and bananas, are healthy.
such as 不能單獨放句首當「例如」使用；應放在名詞後面引出例子。若要句首舉例，改用 For example/For instance。
✗
I like transportation such as I go to school by bike.
✓
I like transportation such as riding a bike to school. / For example, I go to school by bike.
such as 後面要接名詞或名詞片語；若要表動作，用 V-ing 作名詞。若要舉整句例子，改用 For example, + 完整句子。
✗
We need items such as paper, pens, etc.
✓
We need items such as paper and pens. / We need items such as paper, pens, and markers.
such as 已表「例如」，再加 etc. 屬語意重複，正式寫作應避免。
✗
In formal writing: I joined clubs like the basketball team and the choir.
✓
In formal writing: I joined clubs such as the basketball team and the choir.
like 表「像、類似」，不一定是精確例子；在正式寫作中列舉具體例子時，應優先用 such as。
同義詞與反義詞
同義
for example
(例如)
可置於句首或句中，後可接完整句子或片語；語氣上是「舉例說明」，不一定直接接名詞串列。
同義
for instance
(例如)
用法同 for example，常用於句首帶出完整例句。
同義
including
(包括；包含)
強調「包含關係」，通常表示所列項目屬於整體的一部分；語意比 such as 更偏向『包含』而非單純舉例。
