Italian Articles: Il, Lo, La, Gli and the Rule Behind Them

English has one definite article. Italian has seven, and the system is two questions: what gender and number is the noun, and what sound does the next word start with? Gender you learn with the noun. The sound rule explains itself the moment you say it aloud.

The whole system on one screen

Masculine nouns, where all the variety lives:

Feminine nouns, which barely move:

The feminine is la, shortened to l' before a vowel, and le for every plural. All the variety is masculine, and all of it follows the sound of the next word.

Il and la: the default

Most nouns take il (masculine) or la (feminine), and their plurals i and le:

123456

1. 1il pane
2. 2il formaggio
3. 3l'acqua
4. 4il succo
5. 5la frutta
6. 6la torta

Everything on the table takes il or la, except the water: before a vowel la shortens to l’, as the next sections explain.

A noun ending in -o is usually masculine and one in -a usually feminine; plurals and gender has the exceptions.

Lo and gli: a sound rule

lo replaces il, and gli replaces i, before a masculine word starting with:

• lo zainothe rucksack
• lo ziothe uncle
• lo studentethe student

Say il zio out loud. The l slams into the z with no vowel to rest on. Now say lo zio: the vowel gives your tongue somewhere to land. Strictly it is a fixed rule with a history, but the sound is what it grew from, and the sound is the cheapest way to remember it.

The plural does the same job: gli zii, the uncles, and gli studenti, the students, because i zii has the same problem il zio did.

L': the article before a vowel

Before a vowel, lo and la drop their own vowel and become l'. Say lo anno quickly and you get l'anno anyway: the apostrophe is spelling catching up with the mouth.

• l'anno - the year (masculine)
• l'uomo - the man (masculine)
• l'ora - the hour (feminine)

In the plural there is no elision: masculine goes to gli (gli anni, the years) and feminine stays le (le ore, the hours).

The next word decides, not the noun

The sound rule looks at the word straight after the article, which is not always the noun:

The indefinites: un, uno, una, un'

The same sound rule, one more time:

Un takes no apostrophe before a vowel, because it is already a whole word: un anno, a year. Only the feminine shortens: un'ora, an hour. That apostrophe is how you tell the gender of un amico (a male friend) from un'amica (a female friend) on the page.

For some in the plural, Italian uses di fused with the article: dei libri, some books; degli amici, some friends; delle case, some houses.

Articles fused with prepositions

Five prepositions, a, da, di, in and su, merge with a following definite article into one word. It is compulsory:

• Il libro è nella borsa. - The book is in the bag.
• Vado al lavoro. - I'm going to work.
• La casa dello zio. - The uncle's house.

The article inside each fusion follows the same il / lo / la choice, so dello zio and del lavoro. The full chart is in articulated prepositions.

Where Italian uses an article and English does not

Italian puts the definite article in front of general statements, abstract nouns and most possessives:

The one tidy exception: a single family member with a possessive drops it. Mio zio è qui is my uncle is here, but the plural brings the article back (i miei zii, my uncles), and loro always keeps it (il loro zio). Possessives has the rest.

Mistakes English speakers make

What to do next

1. Learn every noun with its article: il tempo, la casa, lo zio.
2. Say il zio aloud once, to hear why lo exists, then stop revising the rule.
3. Move on to the verbs and essere and avere.
