Chinese pronouns are a small closed set - one of the few areas simpler than English.
The core set
| 我 wǒ | I, me | 我们 | we, us |
| 你 nǐ | you | 你们 | you all |
| 他/她/它 tā | he/she/it (one sound) | 他们/她们/它们 | they |
| 您 nín | you, polite | 大家 | everyone |
Spoken Mandarin merges he/she/it into tā - the characters differ, the sound does not. 她 and 它 are twentieth-century print inventions; your ear never has to tell them apart.
们 is not a plural marker
们 attaches to people-pronouns only: 我们, 你们, 老师们. Never on objects (书们 does not exist) and optional even on human nouns - 孩子 already means kid or kids. Think "group of people", not "-s".
Possession and the polite form
Possessive adds 的： 我的, 你的, 他的 (my, your, his). With close people the 的 drops: 我妈, 你爸爸, 他们家. For respect, 您 is the polite singular you - service staff will greet you with it; use it upward, not sideways. Reflexive is 自己 (我自己), and 大家 covers "everyone".
The omissions
Pronouns drop freely once established - Chinese is a pro-drop language. 回答了。 ("answered.") needs no "I"; the subject carries over from context. Subjects also get skipped in questions about the obvious addressee: 吃了吗？ is literally "eaten?" with 你 implied. Learners can use the full form safely - omitting is the fluent habit, not the starting one - but expect natives to drop them constantly in speech and texting.
Common questions
What is the difference between 你 and 您?
您 is polite/respectful - service contexts, elders, formal address. 你 is the default everywhere else. There is no plural 您们 in standard use.
Is there a word for "it" in Chinese?
它 exists but is used far less than English "it" - Chinese prefers repeating the noun or omitting it entirely once the topic is set.
Are there gendered pronouns in spoken Chinese?
No - tā covers he, she and it identically. Gender only appears in writing (他/她/它), which is why spoken slips like "he... she" are famous among learners in both directions.
