Are you ready for a lesson in Italian grammar? Below, Italian teacher Liz T. breaks down the five most difficult Italian grammar rules…
Learning Italian can be difficult, not to mention overwhelming for new students. Many students are afraid of tackling Italian grammar, as it can be complex and confusing at first.
If you take the time to learn Italian grammar, however, you’re much more likely to understand what you’re actually saying, hearing, reading, and writing.
Below, we break down the five most difficult Italian grammar rules to make it easier for you to understand.
1. Nouns and Adjectives
We categorize nouns and adjectives as either masculine and feminine. Typically, nouns ending in -o are masculine, while nouns ending in -a are feminine. See examples below.
- Feminine: “Donna” (woman)
- Masculine: “Uomo” (man)
If the noun ends in -i that means it’s masculine, but plural and nouns ending in -e are feminine, but plural. See examples below.
- Masculine: “Bambini” (children)
- Feminine: “Ragazze” (girls)
2. Singular vs. Plural
Knowing how to create singular and plural nouns can be difficult. While there are a few tricks to remembering the rules, it’s really all about memorizing the endings. See examples below.
Nouns ending in singular -o switch to plural -i
- “Amico” is changed to “Amici” (Friend, Friends)
Nouns ending in singular -a switch to plural -e
- “Torta” is changed to “Torte” (Cake, Cakes)
Nouns ending in singular -ca switch to -che
- “Mucca” is changed to “Mucche” (Cow, Cows)
Nouns ending in singular -e switch to -i
- “Professore” is changed to “Professori” (Professor, Professors)
3. Introducing “The” Definite Articles (Singular)
Singular:
There are two main forms of the definite article in the singular, il (masculine) and la (feminine) and two alternate forms. l’ for any noun starting with a vowel, and –lo, for any masculine noun starting with s- plus a consonant, p-s, or -z. See examples below:
Masculine singular
- Example: “Il gatto” (the cat)
Feminine singular
- Example: “La gatta” (the cat)
Masculine noun starting with a vowel
- Example: “L’uomo” (the man)
Feminine noun starting with a vowel
- Example: “L’amica” (the friend)
Masculine noun starting with a -s plus a consonant
- Example: “Lo Zio” (the uncle)
Plural:
Le is used to describe plural feminine
- “Le Ragazze” replaces La or L’.
I is used to describe plural masculine
- “I Ragazzi” replaces il.
Gli is used to describe plural masculine
- “Gli Zii” replaces Lo or L’.
4. Indefinite Articles “A, An” Describing Nouns
Masculine nouns use “Un” before a vowel or consonant.
- Example: “Un libro” (a book)
Masculine nouns use “Uno” before consonant beginning with -s, -z, -gn, -ps etc.
- Example: “Uno specchio” (a mirror)
Feminine nouns use “Una” before consonant.
- Example: “Una donna” (a woman)
Feminine nouns use “Un” before vowel

Lui and lei mean he and she. Loro means they. There’s a pretty significant difference between subject pronouns and object pronouns in any language. You need to fix that pronoun card in number 5.
Thanks for letting us know, Lori! We’ve fixed it now.
No, I think it’s still wrong on this page?
Nice
The pronoun Lei also is the polite form of ‘you’ in the singular . Surely this should be shown.
