Does he has a ball?

Question

As we know, third person singular uses "has" instead of "have". But why do you say, "Does he have a ball? Yes, he has a ball."

Does this answer your question? In “Does he have it?”, why doesn't ‘have’ agree with ‘he’? — The Photon, Feb 27 '22 at 04:07
The answer to the example question in your post could be "yes, he does have a ball". — The Photon, Feb 27 '22 at 04:08

In BrEng the question would be "*Has he got a ball?" And the short answer would be "Yes, he* *has*". — Mari-Lou A, Feb 27 '22 at 07:30
... but a more idiomatic answer among Brits would be "Yes, he's got one." — Edwin Ashworth, Feb 27 '22 at 14:39

In the sentences "Does he have a ball? Yes, he has a ball." the active verb agrees with the subject:

In "Does he have a ball?", "Does" is the active verb and it agrees with "he"

and

in "Yes, he has a ball", "has" is the active verb and agrees with "he".

In "Does he have a ball?" "Have" is not an active verb - it is the infinitive. Infinitives do not change.

Using the auxiliary verb "do" as the active verb is how English forms questions.
