Italian il vs lo and li vs la: Choosing the Right Definite Article and Forming Plurals
Learn when to use il or lo for masculine singular nouns, and li or la for plural and feminine forms. Master regular plural endings and avoid common article mistakes.
By TheaFirst conversations · Yapr Learn
Italian definite articles change depending on the noun's gender, number, and first sound. This lesson answers two common questions: when to use il versus lo, and when to use li versus la. You will also learn how to form regular plurals by changing the final vowel. By the end, you will be able to choose the correct article and plural form for many everyday nouns.
By the end, you can…
- choose between il and lo based on the initial sound of a masculine noun.
- distinguish li (masculine plural) from la (feminine singular) and form regular plurals.
Listen once. Try it slowly. Then say it without looking.

il libro
the book
eel LEE-broh
Use il before most masculine nouns starting with a consonant, except those beginning with s + consonant, z, gn, ps, x, or y.
lo studente
the student (male)
loh stoo-DEN-teh
Use lo before masculine nouns starting with s + consonant, z, gn, ps, x, or y. Before a vowel, the article is l' (l'amico, l'italiano), not lo.
la casa
the house
lah KAH-zah
Use la for feminine singular nouns starting with a consonant.
gli studenti
the students (male or mixed)
lyee stoo-DEN-tee
Gli is the standard masculine plural definite article before a vowel and before s + consonant, z, gn, ps, x, or y. The older form li is now rare and literary; in modern standard Italian, use gli.
i libri
the books
ee LEE-bree
I is the most common masculine plural article for nouns starting with a consonant (except the special cases that take li or gli).

Make it make sense
Useful pattern
Masculine singular articles: il before most consonants (il libro, il cane); lo before s + consonant, z, gn, ps, x, y (lo studente, lo zaino, lo gnomo); l' before a vowel (l'amico). Masculine plural articles: i before most consonants (i libri); gli before vowels and before the same special sounds (gli studenti, gli zaini, gli amici). Feminine singular: la before consonants (la casa), l' before vowels (l'amica). Feminine plural: le before both consonants and vowels (le case, le amiche). Standard feminine plural le does not elide before vowels.
When to use it
Use il for a masculine singular noun like libro. Use lo for studente because it starts with st-. Use la for a feminine singular noun like casa. Use gli for studenti (masculine plural of studente) because it starts with st-. The older form li is now rare and literary; gli is the standard modern form. Use i for libri. Do not use la for masculine nouns or gli for feminine nouns.
Listen to each line, then take one part and reply out loud.
Scusi, dov'è il libro di italiano?
Excuse me, where is the Italian book?SKOO-zee, doh-VEH eel LEE-broh dee ee-tah-LYAH-noh?Il libro è sul tavolo, vicino allo studente.
The book is on the table, near the student.eel LEE-broh eh sool tah-VOH-loh, vee-CHEE-noh AHL-loh stoo-DEN-teh.Grazie. E dov'è la penna?
Thank you. And where is the pen?GRAH-tsee-eh. eh doh-VEH lah PEN-nah?La penna è nella borsa. Gli studenti hanno i libri e le penne.
The pen is in the bag. The students have the books and the pens.lah PEN-nah eh NEL-lah BOR-sah. lyee stoo-DEN-tee AHN-noh ee LEE-bree eh leh PEN-neh.A little context goes a long way
In modern standard Italian, gli is the normal masculine plural article before vowels and before s + consonant, z, gn, ps, x, or y (gli studenti, gli zaini, gli amici). The older form li is now rare and literary; you may still meet it in older texts, but gli is what speakers actually use. Regional usage varies, but gli is standard everywhere. Always match the article to the noun's gender and number.
One thing to watch for
Using lo before any masculine noun, e.g., saying lo libro instead of il libro.
Try this instead: Use il before most masculine nouns starting with a consonant. Lo is only for special initial sounds like s + consonant, z, gn, ps, x, y. For example, il libro, but lo studente.
Your turn
Try answering out loud before checking a possible answer.
1Choose the correct article: ___ zaino (masculine singular).
Show a sample answer
lo zaino
Zaino starts with z, so it takes lo. Il zaino would be incorrect because il is not used before z.
2What is the plural of la casa?
Show a sample answer
le case
Casa is feminine; its plural is case, with the feminine plural article le: le case. The same article remains before a vowel: le amiche.
3Complete: ___ studenti sono in classe. (masculine plural)
Show a sample answer
Gli studenti
Studenti starts with st-, so the masculine plural article is gli. The older form li is now rare and literary; gli is the standard modern form.
Choose il for most masculine singular nouns, lo for special initial sounds, and l' before vowels. Use la for feminine singular, gli for masculine plural before vowels and special sounds, and le for feminine plural. Always match the article to the noun's gender and number.
