Does English have third-person imperatives, or only second-person ones? Consider:
- Jeff, turn the heat in here way down, please, but don’t anyone turn his suit heater on. We need to get used to that cold as soon as we can. [citation]
The first part is obviously a normal imperative, vocatively addressing Jeff in the second person by using the regular command form.
But what then is the second half? Isn’t anyone always a third-person pronoun? Is this a third-person imperative? Can those even exist? Or has anyone become a second-person pronoun here?
These are not rare, either. This Google Books search comes up with going on a million hits.
But what are they? You can do similar things with someone, everyone, no one, etc. This seems stronger than an indirect command like “Let them eat cake,” because it seems to be actually addressing all these anyone-people.
The thing that throws me about the original citation is that if it is really a second-person in disguise, then why isn’t it
- But don’t everyone turn your suit heater on.
- Everybody give me your opinions.
It almost seems that people randomly pick your, his, and their to match with somebody, anybody, everybody when used in a second-person command:
- Eric get me some water, somebody give up their chair so he can site down. [citation]
If, as John says, this “must” be second person because it is a command, then shouldn’t it “always” be your instead of their? Are there rules about this? Are any of these clearly “right” or clearly “wrong”?
- Somebody give me your ticket.
- Somebody give me their ticket.
- Somebody give me his ticket.
- Somebody give me her ticket.
The first seems to be rare in comparison to the others, so just might be a mistake. But it looks the most correct of any of them to me.
