吧
Meaning
- (modal particle indicating suggestion or surmise)
- ...right?
- ...OK?
How it's used
Softens a sentence into a suggestion or a guess. 我们走吧 is "let's go" rather than "we go". 你是老师吧? is "you're a teacher, right?" — you think so and want confirmation, unlike 吗, which is a genuine question.
Example sentence
我们走吧。
Let's go.
