According to "Alcuno" vs "nessuno" in negative sentences , both adjectives "nessuno" and "alcuno" are correct in negative sentences when they mean "any", although the former is more usual.
Can "alcuno" also be used instead of "nessuno" as a pronoun when it means anybody/nobody ? Is it usual? Example:
- Non è venuto alcuno/nessuno (= Nobody came)
- Non vedo alcuno/nessuno in questa oscurità (= I don't see anybody in this darkness)
WR dictionary says that no, but I'd like to confirm with native speakers.
