Adjectives in Italian are used to describe or modify nouns, providing more information about them. Like nouns, Italian adjectives must agree in gender and number with the noun they modify. This guide will cover the basics of Italian adjectives, including their agreement rules, types, and placement within sentences.

1. Gender and Number Agreement

Italian adjectives must agree with the noun they describe in both gender (masculine or feminine) and number (singular or plural). The endings of adjectives change based on these factors.

1.1 Masculine and Feminine Forms

Most Italian adjectives have different endings for masculine and feminine forms.

• Masculine Singular: Typically ends in -o.
  • Example: bello (beautiful) - un ragazzo bello (a handsome boy)
• Feminine Singular: Typically ends in -a.
  • Example: bella (beautiful) - una ragazza bella (a beautiful girl)
• Masculine Plural: Typically ends in -i.
  • Example: belli (beautiful) - due ragazzi belli (two handsome boys)
• Feminine Plural: Typically ends in -e.
  • Example: belle (beautiful) - due ragazze belle (two beautiful girls)

1.2 Adjectives Ending in -e

Some adjectives end in -e in the singular form for both masculine and feminine nouns. These adjectives only change in the plural form.

• Singular: -e
  • Example: grande (big) - un uomo grande (a big man) / una casa grande (a big house)
• Plural: -i
  • Example: grandi (big) - due uomini grandi (two big men) / due case grandi (two big houses)

1.3 Invariable Adjectives

Some adjectives do not change at all and are the same regardless of the gender and number of the noun they describe.

• Example: blu (blue)
  • un vestito blu (a blue dress) / una macchina blu (a blue car) / i vestiti blu (the blue dresses)

2. Types of Adjectives

2.1 Descriptive Adjectives

These are the most common type of adjectives, providing information about the qualities or characteristics of a noun.

• Alto (tall)
  • Un uomo alto (a tall man)
• Vecchio (old)
  • Una casa vecchia (an old house)
• Felice (happy)
  • Una bambina felice (a happy girl)

2.2 Possessive Adjectives

Possessive adjectives indicate ownership or possession and must agree with the noun in gender and number.

• Mio/Mia/Miei/Mie (my)
  • Il mio libro (my book)
  • La mia casa (my house)
  • I miei amici (my friends)
  • Le mie scarpe (my shoes)

2.3 Demonstrative Adjectives

Demonstrative adjectives point out specific nouns.

• Questo/Questa/Questi/Queste (this/these)

  • Questo libro (this book)
  • Questa penna (this pen)
  • Questi libri (these books)
  • Queste penne (these pens)

• Quello/Quella/Quei/Quelle (that/those)

  • Quel ragazzo (that boy)
  • Quella ragazza (that girl)
  • Quei ragazzi (those boys)
  • Quelle ragazze (those girls)

2.4 Interrogative Adjectives

Interrogative adjectives are used to ask questions about nouns.

• Quale/Quali (which)
  • Quale libro preferisci? (Which book do you prefer?)
  • Quali film ti piacciono? (Which movies do you like?)

3. Placement of Adjectives

3.1 Before the Noun

In Italian, most adjectives follow the noun they describe, unlike in English.

• Una casa grande (A big house)
• Un libro interessante (An interesting book)

3.2 After the Noun

Some adjectives can precede the noun, often to emphasize a subjective or emotional quality.

• Un grande uomo (A great man)
• Una bella giornata (A beautiful day)

3.3 Adjective Meaning Based on Position

The meaning of certain adjectives can change depending on whether they are placed before or after the noun.

• Un vecchio amico (An old friend - someone known for a long time)
• Un amico vecchio (A friend who is old - elderly)

4. Comparative and Superlative Adjectives

4.1 Comparatives

Comparative adjectives are used to compare two nouns.

• Più + adjective + di (more ... than)
  • Maria è più alta di Anna. (Maria is taller than Anna.)
• Meno + adjective + di (less ... than)
  • Questo libro è meno interessante di quello. (This book is less interesting than that one.)
• Così + adjective + come (as ... as)
  • Luca è così intelligente come Marco. (Luca is as intelligent as Marco.)

4.2 Superlatives

Superlative adjectives express the highest degree of a quality.

• Il/La più + adjective (the most ...)
  • Lui è il più bravo della classe. (He is the best in the class.)
• Il/La meno + adjective (the least ...)
  • Questa è la meno costosa. (This is the least expensive.)

4.3 Absolute Superlatives

Absolute superlatives express the extreme quality of something, without comparing it to others. They are often formed by adding -issimo/a/i/e to the adjective's root.

• Bello (beautiful) → Bellissimo (very beautiful)
• Veloce (fast) → Velocissimo (very fast)
