What is the difference between Let's go to the park. Don't we? and Let's go to the park. Shall we? ?Feel free to just provide example sentences.

“Don’t we?” Is grammatically correct on its own, but I believe it is not correct in how it relates to the previous sentence.

“Don’t we?” Is questioning if something is a fact or not, so it really wants to be preceded by a factual statement.

We go to the park on Thursdays. Don’t we?

We still want to go to the park. Don’t we?

I mean, we discussed going to the park. Didn’t we?


But “let’s go…” isn’t stating any kind of fact. It’s a suggestion of something to do. It’s almost like a question, like a request.

“Don’t we?” is asking if there’s a contradiction, but there’s nothing to contradict. You’d need to say:

Let’s go to the park. We do want to go. Don’t we?

“Shall we” just acts as emphasis. A repetition of the request.

Let’s go to the park. Shall we?

Let’s go to the park. Want to?


I hope that makes sense.
