Adjectives ending in -o in the masculine have four forms: Maschile Femminile Singolare -o -a Plurale -i -e il libro italiano la signora italiana i libri italiani le signore italiane il primo giorno la mensa universitaria i primi giorni le mense universitarie If an adjective ends in -io, the o is dropped to form the plural. l'abito vecchio (the old suit)gli abiti vecchi (the old suits)il ragazzo serio (the serious boys)i ragazzi seri (the serious boys) Uli è tedesco. (Uli is German.)Adriana è italiana. (Adriana is Italian.)Roberto e Daniele sono americani. (Robert and Daniel are American.)Svetlana e Natalia sono russe. (Svetlana and Natalia are Russian.) Adjectives ending in -e are the same for the masculine and the feminine singular. In the plural, the -e changes to -i. il ragazzo inglese (the English boy)la ragazza inglese (the English girl)i ragazzi inglesi (the English boys)le ragazze inglesi (the English girls) An adjective modifying two nouns of different gender is masculine. i padri e le madre italiani (Italian fathers and mothers)
