Adjectives
In Italian, adjectives must always agree in both gender (masculine/feminine) and number (singular/plural) with the noun they describe. They also usually come after the noun, unlike in English.

Think of adjectives as shape-shifters. They change their ending letter to match the gender (masculine/feminine) and number (singular/plural) of the noun they describe. They always work as a perfectly matched pair.
Il gatto nero (The black cat) ↔ Le gatte nere (The black cats)
Agreement
Adjectives ending in -o / -a
Most Italian adjectives end in -o in the masculine singular. These have four different forms:
| Singular | Plural | |
|---|---|---|
| Masculine | -o (buono) | -i (buoni) |
| Feminine | -a (buona) | -e (buone) |
Adjectives ending in -e
Some adjectives end in -e. These are easier! They have the same form for masculine and feminine. They only change for singular vs plural:
| Singular | Plural | |
|---|---|---|
| Masc. & Fem. | -e (intelligente) | -i (intelligenti) |
Position of Adjectives
Unlike English, most adjectives in Italian come AFTER the noun they describe.
- Colors: la macchina rossa (the red car)
- Nationalities: un ragazzo italiano (an Italian boy)
- Shapes/Materials: un tavolo rotondo (a round table)
- ⚠️ Exceptions (Before the noun): buono (good), bello (beautiful), bravo (good at), brutto (ugly), nuovo (new), vecchio (old), giovane (young). Example: una bella casa (a beautiful house).
Tricky Adjectives: Buono and Bello
When 'buono' (good) and 'bello' (beautiful) come BEFORE the noun, they change their endings like the indefinite and definite articles!
buono
- Masculine (il/lo): un buon libro, un buono studente
- Feminine (la/l'): una buona pizza, un'buon'amica
bello
- Masculine (il/lo/l'/i/gli): un bel libro, un bello stadio, un bell'amico, bei libri, begli stadi
- Feminine (la/l'/le): una bella casa, una bell'amica, belle case
Tips for Learning
Always check the noun first! The noun is the boss and decides the ending of the adjective.
If the noun ends in -e, check its article (il/la) to know if it's masculine or feminine before matching an -o/-a adjective to it.
Adjectives ending in -ista (optimista, dentista) end in -i for masculine plural and -e for feminine plural.
Colors derived from nouns NEVER change: rosa (pink), viola (purple), blu (blue).
