In tag questions with "Let's," the tag typically uses "shall we?" rather than variations like "will you?" or "would you?" These other forms may not sound entirely natural or idiomatic, though a few are technically possible in informal contexts. Here’s an analysis:
1. Let’s go, will you?
- This is somewhat unusual. It sounds slightly brusque, as if urging someone in a way that could imply impatience. It’s not common but might be used for emphasis.
2. Let’s go, won’t you?
- This is not standard. "Won’t you" is more of a request or invitation in English, so it doesn’t pair naturally with "Let’s." It would usually be, "Come along, won’t you?" rather than "Let’s go, won’t you?"
3. Let’s go, would you?
- This is also unusual and not idiomatic in standard English. It could come across as a bit sarcastic or impatient, depending on the tone.
4. Let’s go, can you?
- This sounds awkward in English, as "can you" implies an ability rather than an encouragement to join.
5. Let’s go, can’t you?
- Also uncommon and not standard. It sounds somewhat confrontational, as if the speaker is frustrated that the person isn’t ready to go yet.
6. Let’s go, could you?
- Similarly to the others, this is not idiomatic. "Could you" implies asking for permission or ability, which doesn’t fit well with "Let’s go."
Correct and Most Natural Tag
The standard, correct form is:
- "Let’s go, shall we?"
Summary of Meaning Differences
The variations in tone among these tags often add a sense of impatience, frustration, or even sarcasm, which is not typical for polite or neutral tag questions. "Shall we" is the only tag that sounds natural and neutral with "Let's go." The other forms may be used in informal or specific situations, but they aren’t grammatically standard.
PS always use "may" rather than "can"
