"Est-ce qu'Anne a un parapluie ?"
Translation:Does Anne have an umbrella?
With, names, he and she, the word used is 'has'. So, he has, she has as well as Mary has, Anne has is the normal usage in English. So, a question by putting does in the the front in my opinion should not change this usage of has.
Are you saying "Does Anne has an umbrella ?" should be accepted ? It isn't a grammatically correct sentence, as only one verb should be conjugated:
he/she/Anne has -> does he/she/Anne have ?
"to do" is conjugated, not "to have", which remains in the infinitive.
- Do I have?
- Do you have?
- Does he/she/it have?
- Do we have?
- Do they have?
