不想 vs 不要: don't want vs don't (imperative)
不想 (bù xiǎng) expresses a lack of desire or unwillingness, usable with any subject. 不要 (búyào) is primarily a negative imperative ('don't do something') or a strong refusal ('I won't have it'). The key difference: 不想 is about internal feeling, while 不要 asserts a command or firm decision.
Both 不想 and 不要 negate desire or action, but they serve different functions. 不想 negates a wish or intention—it means 'I don’t feel like it' and works for any subject (I, you, he, etc.). 不要 is used for negative commands ('don’t do that') or as a strong personal refusal ('I won’t'). The choice depends on whether you are expressing a lack of desire (soft) or issuing a prohibition/refusal (strong).
Quando usar cada um
Use 不想 to express a lack of desire or unwillingness to do something. It applies to any subject (我、你、他, etc.) and is the standard way to say you simply don’t want to do something. It is softer and more about personal feeling.
不想 can also imply a lack of intention without strong emotion. It is never used as a command.
Use 不要 as a negative command meaning 'don’t do something' (e.g., 不要走 'don’t leave'). It can also be used with a verb in first person (我不要去) to express a strong refusal or determination not to do something. With nouns, 不要 means 'don’t want (it)'.
When used in second person or alone as a command, it is imperative. In first person, it is a volitional refusal, stronger than 不想.

Erros comuns
- Using 不要 to express a simple lack of desire (e.g., 我不要去 when you just don't feel like going) sounds too strong or rude; use 不想 for a softer statement.
- Using 不想 as a negative command (e.g., saying 你不想去 to mean 'don't go') – 不想 does not function as an imperative; use 不要 or 别.
- Confusing 不要 with 不能 (cannot): 不要 is about volition/command, not ability or permission. For example, '你不能去' means 'you cannot go' (permission/ability), while '你不要去' means 'don't go' (command).
- Assuming 不要 is only for commands: 不要 can also be a first-person refusal (我不要做) and a polite way to decline offers (不要，谢谢).

- Can I use 不要 to mean 'I don't want' like 不想?
