sentences:  For example, the words "homine" (man) and "femina" (woman) are masculine and feminine, respectively, but "persona" (person) has no gender.Adjectives are invariable and so never have to agree in gender with the nouns they modify.There is a separate nongender pronoun ("illo", "it") and the possessive pronoun "su" ("his", "her" or "its") is gender-neutral.
