在内 zàinèi in it
(included) in it; among them
怎么记住“在内”: 在 at + 内 inside = in it.
汉字
用法
- 在内 (zàinèi) means "included" and almost never stands alone - it nearly always completes the pattern 包括...在内 (bāokuò...zàinèi), "including... ."
- Example: 包括我在内，一共五个人 (bāokuò wǒ zàinèi, yígòng wǔ ge rén) - including me, five people in total.
- It's a fixed bookend to 包括, appearing at the end of the clause it's marking, not as a free-standing verb.
- Formal/written register, common in official counts, lists, and announcements.
