Choose the article with the noun
Italian articles show whether a noun is masculine or feminine, singular or plural. Definite articles refer to an identified noun; indefinite articles introduce one item. English “the” has several Italian forms, so learn an article and its noun together.
Let the next sound guide you
For masculine nouns, use lo before s plus a consonant, z, gn, ps, and some other special initial sounds; use l’ before a vowel. The corresponding plural is gli. Most other masculine nouns use il and i. Feminine nouns use la before a consonant and l’ before a vowel; the plural is le.
Keep the apostrophe in the right place
Use un before masculine nouns, including vowel-initial nouns: un amico. Use uno where lo would appear: uno studente. Feminine una becomes un’ before a vowel: un’amica. The apostrophe marks the loss of the final a, so it does not belong in un amico.
Common article patterns
| Noun pattern | Definite singular → plural | Indefinite singular |
|---|---|---|
| Masculine, ordinary consonant | il libro → i libri | un libro |
| Masculine, s + consonant | lo studente → gli studenti | uno studente |
| Masculine, vowel | l’amico → gli amici | un amico |
| Feminine, consonant | la casa → le case | una casa |
| Feminine, vowel | l’amica → le amiche | un’amica |
This table covers common starting patterns. Articles follow gender and initial sound, not the English translation.
See the pattern in a sentence
Il libro è sul tavolo.
The book is on the table.
Libro is masculine; tavolo uses il inside sul.
Ho un’amica a Roma.
I have a female friend in Rome.
Un’amica is feminine, so the elided article has an apostrophe.
Gli studenti sono in classe.
The students are in class.
Studente starts with s plus a consonant, giving lo and gli.
Common mistakes to notice
To fix: Il studente
Use: Lo studente
Use lo before s followed by a consonant.
To fix: Un’amico
Use: Un amico
Masculine un does not elide; no apostrophe is needed.

Questions about this pattern
How many definite articles does Italian have?
The main forms are il, lo, la, l’, i, gli, and le. L’ serves masculine and feminine singular nouns before a vowel.
Does Italian have a plural indefinite article?
Un and una have no direct plural. Depending on context, use partitives such as dei, degli, and delle, an expression such as alcuni, or no article.
Can I always tell gender from l’?
No. L’acqua is feminine and l’amico is masculine. The elided article hides gender, so learn it with the noun.
