Literally: I have 25 years
J'
I
ai
have
25 ans
25 years
Good to know
The question is Tu as quel âge ? informally, or Quel âge avez-vous ? formally. Both use avoir, so the answer does too.
Correct
J'ai 25 ans
What people say wrong
Je suis 25 ans
ungrammatical in French
The mistake to avoid. Age is something you have in French, not something you are. And ans is never optional the way years old is in English. J'ai 25 gets you a blank look; j'ai 25 ans is the whole sentence.
In context
J'ai vingt-cinq ans.
I'm twenty-five.
Tu as quel âge ?
How old are you?
Ma fille a huit ans aujourd'hui.
My daughter is eight today.
