对了

对了 is an interjection used to express agreement, realization, or to introduce a new point. It often conveys a sense of confirmation or sudden understanding, similar to 'Oh, right!' or 'That's right!' in English.

The character 对 (duì) means 'correct' or 'right,' while 了 (le) is a particle indicating completion or a change in state. Together, they form a phrase that signals a realization or affirmation.

It is commonly used in casual conversation to acknowledge something just remembered or to transition to a new topic. For example, someone might say 对了 when they suddenly recall an important detail during a conversation.
