Italian Adjective Agreement and Position

Level: A1. In Italian an adjective must match its noun — in gender (masculine/feminine) and number (singular/plural) — and it usually comes after the noun. Learn the two ending patterns and a short list of adjectives that go in front.

The rule

An adjective describes a noun (red, big, new). To agree means the adjective changes its ending to match the noun’s gender and number. There are two classes.

Class 1 — adjectives ending in -o. These have four forms: masculine singular -o, feminine singular -a, masculine plural -i, feminine plural -e. So rosso (red) gives rosso / rossa / rossi / rosse.

Class 2 — adjectives ending in -e. These have only two forms: -e for both genders in the singular, -i for both genders in the plural. So grande (big) gives grande / grande / grandi / grandi. The singular looks the same for a man or a woman; only the plural changes.

Most adjectives follow the noun: una casa rossa (a red house), un libro interessante (an interesting book). But a small group of very common adjectives usually comes before the noun — bello, buono, bravo, grande, piccolo, nuovo, vecchio, giovane, brutto — and some of these can change the article-like shape or even the meaning.

The endings at a glance

And the two front-position shape-shifters, before the noun:

How to say it

A few Italian sounds decide how these endings are read:

• Double consonants are held longer: rosso (“ROHS-so”), bello (“BEHL-lo”) — don’t shorten them to a single sound.
• c / g before e or i are soft: c = “ch” (piacere), g = “j” (giovane = “JOH-vah-neh”); before a/o/u they are hard (grande = hard “g”).
• ch / gh keep the hard sound before e/i: bianche = “bee-AN-keh”.
• gli is a soft “lly” sound: begli ≈ “BEH-lyee”.
• every final vowel is pronounced: rosse is two syllables, “ROHS-seh”.

Example sentences

Common mistakes

• ❌ una casa rosso → ✅ una casa rossa. Casa is feminine singular, so the -o adjective takes -a.
• ❌ due case rossi → ✅ due case rosse. Feminine plural of an -o adjective is -e, not -i.
• ❌ una lezione interessanta → ✅ una lezione interessante. An -e adjective does not switch to -a in the feminine; it stays -e.
• ❌ un bello ragazzo → ✅ un bel ragazzo. Before most masculine nouns bello shortens to bel.
• ❌ un buono libro → ✅ un buon libro. Before a masculine noun buono drops to buon.
• ❌ una rossa casa → ✅ una casa rossa. A colour adjective follows the noun; don’t put it in front like in English.

A short conversation

Al mercato (at the market): — Che bella borsa! È nuova? — Sì, è una borsa italiana, molto comoda. — E quelle scarpe rosse? — Sono vecchie, ma buone. Un buon affare!

Usage notes

• Position and meaning. Many adjectives mean something different before vs after the noun: un grande uomo (a great man) vs un uomo grande (a big man); un vecchio amico (a long-time friend) vs un amico vecchio (an elderly friend).
• bello and buono before the noun. bello follows the pattern of the definite article (bel like il, bello like lo, begli like gli). buono in the singular follows the indefinite article (buon like un, buono like uno, buona like una). After the noun they are regular: un ragazzo bello, un libro buono.
• Nouns ending in -e. Because an -e noun hides its gender, you must learn the gender to choose the adjective: il fiore is masculine (un fiore rosso), la neve is feminine (la neve bianca).
• molto as an adverb doesn’t agree. molto meaning “very” never changes: una casa molto grande, ragazze molto alte.

Compared with…

• Noun gender — the adjective can only agree once you know the noun’s gender, so start there: see Italian Noun Gender.
• Plural of nouns and adjectives — the same -i / -e / -a plural endings run through both: compare Plurals of Nouns and Adjectives.
