"She adds that she does not have sisters." how it can be correct, they put here have when if i use she i need to put has not have, is it an error or i don't understand something? can someone explain this to me, i know its the Italian language lessons but English its not my native language. thank you!
When using an auxiliary, in English as well as in Italian, only the auxiliary is conjugated while the main verb becomes infinitive; "she is" but "she can be", and "she knows" but "she doesn't know". In the same way in this sentence it could be "she has no sisters" or (with the auxiliary "do") "she doesn't have sisters". As you can see English and Italian form their negatives in different ways.
