I was just trying to formulate a sentence in an email, and wanted to reference a third person, inquiring as to which of something that person was referring in the forwarded mail message.

Is it:

"About which things is he talking?"


"About which things are he talking?"

Just FYI I originally had the "about" at the end. Not grammatically correct but no one talks like that anyway.

There seem to be conflicting rules here, but I don't know which one applies. Normally, with sentences like "What is he doing?" the "is" is part of "is talking," and similarly the second person "are talking." This would indicate that the first version is correct. But you could also argue that the helper verb applies to "things", and so should be "are" because "things" is plural.

I started to think that "is he" is correct, because if you turn the sentence around to answer it, you get "He is talking about those things" and not "he are talking". But still, there are other sentences like "Which gifts is he bringing to the party?" Now that just feels wrong, saying "gifts is" like that. But is it correct?

  • The verb should pertain to "he" (since the answer would go like "he is talking about..."); thus, use the singular verb, "is".

    You could not "also argue that the helper verb applies to 'things', and so should be 'are' because 'things' is plural". That's because the verb does not apply to "things".

  • i.e., "things" is not the subject, but "he", for that example.

    BTW, there's nothing wrong with putting "about" at the end! Dec 13, 2010 at 16:27
  • "What were you talking about?"

As, he is the subject of the sentence here, you need to match the singular, so the correct construction uses is.

About which things is he talking?

Similarly, your other example also needs is for the same reason.

Which gifts is he bringing to the party?

Things and gifts are the objects of these verbs and not the subjects so don't let them fool you. Imagine replacing them with what, for example and see how it sounds.

What is he bringing to the party?


What are he bringing to the party?

  • Thanks for clarifying. English is messed up, even when it's correct.

    English is not messed up. This is fairly logical and you'll find it in other European languages as well.

The subject of both sentences —the person doing the talking or bringing— is he, which requires the singular "is". (As RegDwight noted, you could not "also argue that the helper verb applies to 'things'". Well, ok, you could argue it, but you'd be wrong.)

What things is he talking about?
Which gifts is he bringing to the party?

Note that it is not only perfectly grammatical to put about at the end, but it also flows better, so lots of people do indeed "talk that way".

  • I meant nobody says "about which is he talking" in casual conversation. Everyone does say "which is he talking about." I guess I was a bit confusing there.
