自己 vs 本人 (zìjǐ vs běnrén): which reflexive to use
自己 is the everyday reflexive pronoun meaning 'self', used for actions directed at the subject or for emphasis. 本人 is a formal term meaning 'the person in question' or 'I/me' in official contexts, often used in written documents and formal introductions. Choose 自己 for general reflexive use and 本人 for formal, impersonal reference.
Both 自己 and 本人 function as reflexive pronouns, but they differ in register and usage. 自己 is neutral and versatile, covering reflexive actions (e.g., 'self' as object), emphasis (e.g., 'by oneself'), and colloquial contexts. 本人 is formal and impersonal, typically used in official, legal, or written settings to refer to 'the person in question' (including the speaker/writer in a detached manner). Understanding the register and context is key to choosing the correct term.
When to use each
Use 自己 for most reflexive situations in everyday speech and writing. It can indicate the subject performing an action on itself ('myself', 'yourself', 'himself', etc.), emphasize that something is done without help ('by oneself'), or simply mean 'one's own'. It is also used in compound expressions like 我自己 (wǒ zìjǐ) or 你自己 (nǐ zìjǐ).
Use 本人 in formal, official, or legal contexts to refer to 'the person in question' or 'I/me' (when the speaker is writing formally). It often appears in documents, announcements, or formal introductions where a neutral, impersonal tone is required. For example, 本人表示同意 (the person in question agrees) or 本人姓张 (I, Zhang, in a formal statement).
Although 本人 can refer to the speaker (first person), it avoids the personal connotations of 我 (wǒ) and is used for detachment or politeness in formal writing.

FAQ
- When do I use 自己 vs 本人 in a formal letter?
- Use 本人 to refer to yourself as the writer when you want to maintain a formal, objective tone (e.g., 本人谨此声明...). Use 自己 only if you are talking about reflexive actions or emphasis (e.g., 'I myself...') which is less common in very formal writing.
- Is 本人 always formal?
- Yes, 本人 is strongly associated with formal, written, or official contexts. Avoid using it in everyday speech; use 自己 or personal pronouns instead.
- Can 自己 be used without a preceding pronoun?
- Yes, 自己 can stand alone as a reflexive pronoun meaning 'oneself' in general statements, e.g., 照顾自己是重要的 (It is important to take care of oneself). However, it often requires context to specify the subject.
