When do I use 好 vs 对 as resultative complements?

Use 好 when you want to say the action is done well, thoroughly, or the object is ready for use. Use 对 when you want to say the action or its result is factually correct. For example, 写好 (write out, finished) vs 写对 (write correctly).

Can I use 好 and 对 together, like 做好对?

No, you generally cannot combine two resultative complements directly. If you need to express both completeness and correctness, you can use separate clauses or a different structure, e.g., 已经做好了，而且也都做对了 (It's already done well, and everything is correct).

Do 好 and 对 always imply the action is finished?

好 typically implies that the action is finished and the result is in a good state. 对 does not necessarily imply completion; you can say 想对 (think correctly) about a past thought or a current conclusion, but it does not guarantee the entire task is done.

好 vs 对 (hǎo vs duì): resultative complements for 'done well' vs 'correctly'

When used as resultative verb complements, 好 (hǎo) indicates that an action is performed well, thoroughly, or that the object is ready for use. 对 (duì) indicates that the result is factually correct or matches a standard. Choose 好 for completion and readiness, and 对 for accuracy.

Both 好 and 对 can function as resultative complements placed after a verb to describe the result of an action. They differ in what aspect of the result they emphasize: 好 stresses that the action is carried out well, thoroughly, or that the object is in a ready state, while 对 stresses that the result is correct, accurate, or follows a norm. Understanding this distinction helps avoid common mistakes when expressing whether something is 'done properly' versus 'done correctly'.

Quando usar cada um

好hǎo

done well (ready)

Use 好 after a verb when you want to say that the action was performed thoroughly, properly, or to a satisfactory degree. It often implies the completion of an action with a good or ready result, such as cooking a meal (做好), repairing something (修好), or preparing something (准备好).

In some contexts, 好 can also imply that the object is in a usable or finished state, not just 'well done'. For example, 写好 (xiě hǎo) means 'written out' or 'finished writing', while 写对 (xiě duì) means 'written correctly'.

对duì

correctly (right)

Use 对 after a verb to indicate that the action or its result is correct, accurate, or matches a standard. It is common with verbs involving thought, choice, or verification, such as 想对 (think correctly), 做对 (do correctly), 说对 (say correctly).

对 focuses solely on factual correctness and does not imply completion in the sense of being 'ready'. Something can be 做对 (done correctly) but still not be 做好 (done well/finished) if additional steps are needed.
