Bonjour Madame Cécile !
A sentence came up while I was reviewing the lesson-
Il a déjà acheté un nouvel appartement.
To form the negative, I think it should be-
Il n’a pas encore acheté de nouvel appartement.
I had read the rule in the following lesson that “un” changes to “de” in negative sentences-
Un/une become de/d' in negative sentences in French (French Indefinite Articles)
But, will “un” change to “de” in this negation ? Because, there is an adjective after “un” ?
Is this an exceptional case where the above mentioned rule does not apply as it happens for “Verbs of State” ?
Merci en avance ! Je vous souhaite une bonne journée!
À bientôt !
