Using 吧 For Suggestion
走吧 zǒuba was the common phrase we used to express that “吧” can indicate a suggestion. When used in this way, it has a similar function as “Let’s [insert suggestion here]” in English (e.g., “let’s go”). The grammar is the opposite of course because 吧 always goes at the end of a sentence. It is incredibly simple when it has this function, so look out for it when Chinese people are speaking around you and potentially making decisions together.
Using 吧 For Educated Guesses
It has a second use that is related, but not exactly the same: an educated guess. It’s like you are “suggesting” what the reason is for some observed phenomenon. For example, suppose you were at your friend’s house, and she has a little daughter who is a toddler, but your friend’s daughter looks a bit uncomfortable or upset. In Chinese, you might say “她饿了吧？tā è le ba?”, which means “She’s probably hungry, right?”. It isn’t as clear a suggestion as “Let’s go eat” (我们一起出去吃饭吧 wǒmen yìqǐ chūqu chīfàn ba”), but it is a suggestion as to why your friend’s toddler is looking uncomfortable.
Does It Have A Question Mark?
Effectively, if it is a simple suggestion, there is no question mark. If it is an educated guess, there is still some level of uncertainty and therefore will usually have a question mark. Consider three prevalent words and what they mean if they have 吧 after them.
好吧 & The Chinese Sax Player
Take 好吧 for example. The first time Phil understood the “educated guess” version of “吧” was when he saw it used rhetorically. While in Inner Mongolia playing a gig with his band, Phil observed a Chinese saxophone player doing a solo performance on stage with a background music track. This guy was full of charisma, and he would say things like “I’m gonna play a song by [Insert famous Chinese pop start here], 好吧？！.”
In this context, “好吧” is making the educated guess that the audience is going to be OK with (好) the following song. He’s not 50/50, he’s confident. Technically it is still a question (hence the question mark), but it implies that he’s pretty sure the audience isn’t going to respond with “No, get off the stage!”.
Both 对吧 and 是吧 function the same way. 对 means “correct,” so if you say “对吧？,” it has the same tone you have when confirming something you are nearly certain is true. For example, “The Eagles won the most recent super bowl, right? (对吧?).. Seeing as “是” just means “is,”` saying “是吧” means “isn’t it?”.
