When using sure/indefinite pronouns does no longer correspond to what you're used to in English, you feel of it as a elimination. But French was once very influential within the formation of English. Maybe that's why it sort of feels extra natural to you. What if the French and English are noticeable as including on useless pronouns as an alternative of the opposite? It is all for your factor of view. For illustration, in Spanish we are saying Soy dentista. It involves the entire imperative understanding. In English we might say I am A dentist.

Soy already involves the I, and there's no likelihood that one man or woman can also be multiple dentist, so the singular indefinite article is simply superfluous.
