**CIRA COMMON · Grammar Library | A1–A2 | Spanish (Spain)**

## Quick answer

Spanish has two main article families. **Indefinite articles** (*un, una, unos, unas*) introduce a person or thing, identify a member of a category, or refer to an unspecified quantity. **Definite articles** (*el, la, los, las*) point to something identifiable in context, something unique in the situation, or a category in general.

Compare: **He visto un perro en el parque.** — *I've seen a dog in the park.* **El perro llevaba un pañuelo rojo.** — *The dog was wearing a red bandana.* The dog becomes identifiable after its first mention.

## 1\. The eight basic forms

| Number   | Gender    | Indefinite | Definite |
| -------- | --------- | ---------- | -------- |
| Singular | Masculine | **un**     | **el**   |
| Singular | Feminine  | **una**    | **la**   |
| Plural   | Masculine | **unos**   | **los**  |
| Plural   | Feminine  | **unas**   | **las**  |

The article normally agrees with its noun in **gender** and **number**. *Un abrigo* (a coat) becomes *unos abrigos* (some coats); *la ventana* (the window) becomes *las ventanas* (the windows). A mixed-gender plural group normally takes the masculine plural form: *los vecinos* (the neighbours).

## 2\. When to use an indefinite article

### First mention: something new to the listener

**Hay una panadería cerca de mi casa.** — *There's a bakery near my house.* The listener has not yet been told which bakery.

### One example of a class

**Mi prima es una persona muy paciente.** — *My cousin is a very patient person.* She is being described as a member of a category.

### One item, some items, or an approximate amount

**Necesito un billete de tren.** — *I need a train ticket.*

**He comprado unas mandarinas.** — *I've bought some mandarins.*

**Tardaremos unos veinte minutos.** — *It'll take us about twenty minutes.* Here *unos* means *approximately*.

Sometimes plural **unos/unas** means an unspecified number; with nouns normally used only in the plural, it can indicate one set: **Necesito unas gafas nuevas.** — *I need a new pair of glasses.*

## 3\. When to use a definite article

### Previously mentioned or clearly identifiable

**Hay una bicicleta junto al portal. La bicicleta es azul.** — *There's a bicycle by the entrance. The bicycle is blue.*

**Cierra la ventana, por favor.** — *Close the window, please.* The context makes it clear which window.

### A person or thing unique in context

**La directora del colegio está de vacaciones.** — *The headteacher of the school is on holiday.* The role identifies the person within this school.

### A whole class or an idea in general

**Los gatos necesitan descansar.** — *Cats need rest.*

**Me gusta el chocolate negro.** — *I like dark chocolate.* English often omits *the* in such general statements; Spanish frequently uses the definite article.

## 4\. A practical contrast: un versus el

**First mention → known item:** **Veo un coche aparcado. El coche tiene la puerta abierta.** — *I see a parked car. The car has its door open.*

**Any member → identified member:** **Busco una farmacia.** — *I'm looking for a pharmacy.* / **Busco la farmacia que está junto al mercado.** — *I'm looking for the pharmacy next to the market.*

**Quantity → general category:** **Quiero unas fresas.** — *I'd like some strawberries.* / **Me encantan las fresas.** — *I love strawberries.*

Choosing between articles depends on **what the listener can identify**, not simply whether an object exists.

## 5\. Feminine nouns beginning with stressed a- or ha-

Some **feminine singular** nouns beginning with a **stressed** /a/ sound take **el** instead of *la*, and **un** instead of *una* when the article immediately precedes the noun:

**el agua fría** — *the cold water*; **un águila enorme** — *a huge eagle*; **el hacha afilada** — *the sharp axe*.

The noun is **still feminine**: any adjective agrees in the feminine, as in *agua fría*. In the plural, use the regular feminine articles: **las aguas**, **unas águilas**. If another word comes between the article and the noun, the feminine article returns: **la misma agua**, **una enorme águila**. A silent *h* does not affect the rule; stress does. Therefore we say **la harina**, because the first *a* sound is not stressed.

> Remember: **el agua fría**, not *el agua frío*. The special article form does **not** change the noun's gender.

## 6\. The contractions al and del

In ordinary use, **a + el → al** and **de + el → del**:

**Vamos al museo.** — *We're going to the museum.*

**Vengo del supermercado.** — *I'm coming from the supermarket.*

There is no matching contraction with *la*, *los*, or *las*: **a la oficina**, **de las tiendas**. Nor do *a él* and *de él* contract, because **él** is a pronoun, not an article. Proper-name cases in which *El* forms part of an official title or name require separate treatment.

## 7\. What about no article?

Spanish does **not** require an article with every noun. In straightforward professions after *ser*, an article is usually absent: **Mi hermano es enfermero.** — *My brother is a nurse.* Adding a qualifying description can favour an indefinite article: **Es un enfermero excelente.** — *He's an excellent nurse.*

Bare plural or mass nouns are also possible when talking about an unspecified amount: **Compramos pan y tomates.** — *We buy bread and tomatoes.* But **Compramos el pan y los tomates** refers to identifiable bread and tomatoes. Article omission is a broader topic covered by **GRAM A-005** and is not taught exhaustively here.

## 8\. Common mistakes

| Avoid                                          | Say                     | Why                                                                 |
| ---------------------------------------------- | ----------------------- | ------------------------------------------------------------------- |
| *la agua fría*                                 | **el agua fría**        | Stressed initial /a/ in feminine singular nouns.                    |
| *el agua frío*                                 | **el agua fría**        | The noun remains feminine.                                          |
| *Voy a el mercado*                             | **Voy al mercado**      | Contract *a + el*.                                                  |
| *Vengo de el trabajo*                          | **Vengo del trabajo**   | Contract *de + el*.                                                 |
| *Me gustan gatos*                              | **Me gustan los gatos** | A general category commonly takes the definite article.             |
| *Soy un médico* (neutral profession statement) | **Soy médico**          | The unmodified profession is normally expressed without an article. |

The last example is a **default**, not an absolute prohibition: *Soy un médico con mucha experiencia* is natural because the noun phrase includes a qualification.

## 9\. Remember

Use **un/una/unos/unas** to introduce something new, mean *one/some*, or describe one member of a category. Use **el/la/los/las** when the referent is identifiable, unique in context, or a general category. Check gender and number; remember feminine **el agua**, **un águila**, and the contractions **al/del**. Sometimes the right choice is **no article**—a related rule, not a third article family.
