> Esperanto has one article, la ("the"), and no word for "a". It never changes: la domo, la domojn. When to use it, when to leave it out, and what l' means.

Esperanto has a single article, *la*, meaning "the". It never changes for gender, number or case: *la domo* – "the house", *la domoj* – "the houses", *la domojn* – "the houses" (as object). There is no indefinite article: *domo* means "a house" or simply "house".

Rule 1 of the [16 rules](https://esperantopedia.org/grammar/16-rules/) sets this out, and it even lets beginners leave *la* out at first. In practice every fluent speaker uses it, and its use is close to English "the".

## When to use la

Use *la* when the listener knows which thing you mean. PMEG sums up its meaning as "you know which one I mean".

| Situation | Example | Translation |
|---|---|---|
| Mentioned before | *Mi vidis hundon. La hundo estis nigra.* | "I saw a dog. The dog was black." |
| Clear from the situation | *Mi luis aŭton, sed la radio ne funkciis.* | "I rented a car, but the radio didn't work." |
| Defined in the sentence | *la ĉapelo de mia patro* | "my father's hat" |
| Only one exists | *la suno, la ĉielo* | "the sun, the sky" |
| Superlatives | *la plej alta monto* | "the highest mountain" |
| Languages named with *-a* | *la angla, la pola* | "English, Polish" |
| Names made of ordinary words | *la Nigra Maro, la Alpoj* | "the Black Sea, the Alps" |

Language names like *la angla* are short for *la angla lingvo* – "the English language". That is why they need *la*, unlike English.

## When not to use la

- **Something new or unknown.** *Hundo bojas.* – "A dog is barking."
- **With other determiners.** *Mia*, *tiu*, *ĉiu* and similar words already make the noun definite: *mia libro* – "my book", *tiu domo* – "that house". Never *la mia libro* or *la tiu domo*.
- **Most proper names.** *Petro*, *Londono*, *Japanio* – and *Esperanto* itself: *Mi lernas Esperanton.* – "I am learning Esperanto."
- **Things in general.** *Mi trinkas kafon.* – "I drink coffee." Compare *La kafo estas varma.* – "The coffee is hot" (this particular coffee).

A possessive with *la* can stand alone, meaning "mine", "yours" and so on: *Via aŭto estas ruĝa, la mia estas blua.* – "Your car is red, mine is blue." See [pronouns](https://esperantopedia.org/grammar/pronouns/).

## Talking about a whole kind

To speak about a species or type, Esperanto has three options:

- *Ĉevalo estas besto.* – "A horse is an animal."
- *Ĉevaloj estas bestoj.* – "Horses are animals."
- *La ĉevalo estas utila besto.* – "The horse is a useful animal."

According to PMEG, the form without *la* is the most common, while *la* presents the whole species as one known individual and sounds more formal.

## Special uses

- **Body parts and clothing.** When the owner is obvious, *la* replaces the possessive: *Li levis la manon.* – "He raised his hand."
- **"All" of a known group.** *La gastoj eksidis.* – "The guests sat down" (all of them).
- **Royal names.** *La* comes after the name: *Karolo la Granda* – "Charles the Great".

## The short form l'

Rule 16 allows *l'* instead of *la*. PMEG recommends it only after a preposition ending in a vowel, such as *de*, *pri*, *tra* or *je*: *de l' mondo* – "of the world", *pri l' amo* – "about love".

It is written as a separate word but pronounced together with the preposition, as one unit. Outside poetry and songs *l'* is rare, and in speech it hardly occurs.

## La compared with English "the"

| Point | English | Esperanto |
|---|---|---|
| Indefinite article | "a, an" | none: *libro* – "a book" |
| Language names | "English" | *la angla* |
| Body parts | "his hand" | *la mano* is common |
| Country names | "the Netherlands" | *Nederlando*, no article |
| Changes with case or number | no | no: *la domojn* |

When you need to stress "one" or "a certain", use *unu* or *iu*: *Iu viro telefonis.* – "Some man phoned." See [correlatives](https://esperantopedia.org/grammar/correlatives/).

## Examples in sentences

- *La suno brilas.* – "The sun is shining."
- *Mi aĉetis libron. La libro estas tre interesa.* – "I bought a book. The book is very interesting."
- *Ĉu vi vidis la ŝlosilojn?* – "Have you seen the keys?"
- *Hundoj estas fidelaj bestoj.* – "Dogs are loyal animals."
- *La hundo estas fidela besto.* – "The dog is a loyal animal."
- *Mi ŝatas muzikon.* – "I like music."
- *Esperanto estas facila lingvo.* – "Esperanto is an easy language."
- *La esperanta lingvo naskiĝis en 1887.* – "The Esperanto language was born in 1887."
- *Mi loĝas en la ĉefurbo de Pollando.* – "I live in the capital of Poland."

## Common questions

### Is there a word for "a" or "an" in Esperanto?
No. A noun without *la* is indefinite: *libro* – "a book". To stress "one" or "a certain", use *unu* or *iu*.

### Does la change in the plural or in the accusative?
No. *La* never takes *-j* or *-n*: *la grandajn domojn* – "the big houses" (as object). Only the noun and its adjectives change, as explained on [nouns and adjectives](https://esperantopedia.org/grammar/nouns-adjectives/).

### What does l' mean in Esperanto?
It is a shortened *la*, allowed by rule 16. It appears mostly in poetry and songs, after prepositions like *de* or *pri*: *de l' mondo* – "of the world".

### Do you say "la Esperanto"?
No. *Esperanto* is a proper name: *Mi parolas Esperanton.* – "I speak Esperanto." Language names formed with *-a* take the article: *la angla* – "English".
