From Latin nē (“not”) + ipse (emphatic, literally “himself”) + ūnus (“one”), meaning “not even one”. Cognate with Neapolitan nisciuno, Friulian nissun, Ligurian nisciǜn, and Old French neisune. Compare Spanish ninguno and Romanian niciun.
nessuno m sg (feminine nessuna)
- The adjectival form has no plural form and is therefore only used with singular nouns. The pronoun is also a singulare tantum.
- Before any grammatically connected word not beginning with s + consonant, cn, gn, pn, ps, x, or z, the masculine form nessuno changes into the apocopic form nessun, while the feminine form nessuna becomes nessun' before vowels:
nessun dolore ― no pain
nessun amico ― no friends
nessun'amica ― no (female) friends
nessun altro ― nobody else
