Appropriate
Avoid when
The most common way is 是的 (shì de), which literally means 'it is so'. You can also use 对 (duì) or 没错 (méi cuò) for 'correct' or 'that's right'.
It is pronounced 'shì de'. The first syllable 'shì' has a falling tone, and the second syllable 'de' is neutral and unstressed.
是的 is slightly more formal and emphasizes confirmation, while 对 is more casual and means 'correct'. Both can be used to agree, but 是的 is better for formal settings or when you want to be polite.
