-a → -i (Masculine)
-e → -i (Both genders)
-o → -i (Feminine, e.g., la mano)
How It Works
To become proficient in Italian plurals, you must look at both the ending and the gender of the noun:
- Nouns in -o: Usually masculine, change to -i (libro → libri). Note: la mano (feminine) also becomes le mani.
- Nouns in -a: Feminine nouns change to -e (casa → case). Masculine nouns in -a change to -i (problema → problemi).
- Nouns in -e: Both genders change to -i (fiore → fiori, chiave → chiavi).
Spelling Rules:
- -ca/-ga: Add 'h' to keep the hard sound (amica → amiche).
- -co/-go: Usually add 'h' if stressed on the penultimate syllable (fuo-co → fuochi), but change to -ci/-gi if stressed on the antepenultimate (me-di-co → medici).
- -cia/-gia: Drop the 'i' if a consonant precedes the ending (pioggia → piogge); keep it if a vowel precedes (camicia → camicie).
- -io: If the 'i' is stressed, keep it (zìo → zii); if unstressed, use one 'i' (ufficio → uffici).
Invariable Nouns:
These do not change: accented vowels (città), monosyllables (re, tè), nouns ending in -i (crisi), consonants (film), and abbreviations (foto).
Common Irregulars:
l'uomo → gli uomini, l'uovo → le uova, il dito → le dita.

Common Mistakes
Applying the feminine -e ending to masculine nouns ending in -a.
I probleme.I problemi.Masculine nouns ending in -a (often of Greek origin like 'problema', 'tema', 'clima') always take the masculine plural ending -i.
Adding an 's' to form the plural.
Due gattos.Due gatti.Italian plurals are formed by changing the final vowel, never by adding 's'.
Keeping the 'i' in -cia/-gia plurals when it is not needed.
Le arancie.Le arance.If -cia or -gia is preceded by a consonant, the 'i' is dropped in the plural. If preceded by a vowel (like 'camicia'), the 'i' is kept ('camicie').
