Adjective Number Agreement

Just as Italian adjectives must agree in gender, they must also agree in number — singular or plural. This lesson focuses on the plural forms of adjectives, including the regular patterns and the important spelling rules that apply to certain consonant endings.

Regular Plural Formation

The regular rules for making adjectives plural are straightforward:

Singular Ending	Plural Ending	Example
-o (masc.)	-i	rosso → rossi
-a (fem.)	-e	rossa → rosse
-e (masc. or fem.)	-i	grande → grandi

il gatto nero     →  i gatti neri      (the black cats, masc.)
la gonna nera     →  le gonne nere     (the black skirts, fem.)
il ponte grande   →  i ponti grandi    (the big bridges, masc.)
la città grande   →  le città grandi   (the big cities, fem.)

Tip: The plural rules for adjectives mirror the plural rules for nouns. Learn one set and you learn both.
