The Preposition A in Spanish

The Spanish preposition a often means to or at, but it also appears in several common grammar patterns where there is no direct English equivalent.

For beginners, the most useful uses are:

a + place → movement toward a place
a + person → with some verbs such as gustar
personal a → before a person who is the direct object
ir a + infinitive → going to do something

A for movement: to

Use a when someone or something moves toward a place.

Voy a Madrid. — I’m going to Madrid.
Vamos al supermercado. — We’re going to the supermarket.
Llego a casa a las ocho. — I arrive home at eight.

With el, a + el becomes al:

Voy al banco.
Vamos al parque.

But a + la does not contract:

Voy a la escuela.

A with people: to someone

With verbs such as gustar, a + person tells us who experiences the feeling or reaction.

A Marta le gusta el café. — Marta likes coffee.
A Pablo le encantan los perros. — Pablo loves dogs.
A mis padres les interesa la historia. — My parents are interested in history.

Here, a Marta can be understood as “to Marta.”

A useful way to understand:

Le gusta el café a Marta.≈ The coffee is pleasing to Marta.

In normal Spanish, a Marta is often placed at the beginning:

A Marta le gusta el café.

The indirect object pronoun is still used:

✅ A Marta le gusta el café.
❌ A Marta gusta el café.

This use of a is different from the personal a below.

The personal a

Spanish normally uses a before a specific person who is the direct object of a verb.

Compare:

Veo la casa. — I see the house.
Veo a Marta. — I see Marta.

Marta is the person being seen, so Spanish uses the personal a.

More examples:

Conozco a Carlos. — I know Carlos.
Llamo a mi madre. — I call my mother.
Busco a Ana. — I’m looking for Ana.

The a usually does not translate into English.

Person vs thing

Compare:

Busco mi teléfono. — I’m looking for my phone.
Busco a mi hermano. — I’m looking for my brother.

Use the personal a with people, but normally not with things.

A + infinitive with ir

Use:

ir + a + infinitive

to talk about something you are going to do.

Voy a estudiar. — I’m going to study.
Vamos a comer. — We’re going to eat.
¿Qué vas a hacer? — What are you going to do?

Here, a is part of the structure ir a + infinitive.

See ir a + infinitive for more examples.

A for time

Use a before a specific clock time to say at.

La clase empieza a las nueve. — The class starts at nine.
Como a la una. — I eat at one.
Nos vemos a las seis. — See you at six.
La clase empieza a las ocho. — The class starts at eight.
Nos vemos a las seis. — See you at six.
Trabajo a las nueve. — I work at nine. If you need to review Spanish numbers, see numbers and the calendar.

Use a la with one o’clock and a las with other hours.

a la una — at one o’clock
a las dos / tres / cuatro… — at two / three / four…

This is because hora (hour) is feminine: la una, las dos, las tres.

Compare this with telling time:

Son las ocho. — It is eight o’clock.
La clase empieza a las ocho. — The class starts at eight.

Use a when the time tells you when an action happens.

A few common expressions

You will also see a in many common expressions:

a veces — sometimes
a pie — on foot
a casa — home / to home
al lado de — next to

These are best learned as complete expressions.

Watch out: not every a + person is the personal a

These two sentences both contain a Marta, but the grammar is different:

Veo a Marta. — I see Marta.
A Marta le gusta el café. — Marta likes coffee.

In Veo a Marta, Marta is the direct object, so this is the personal a.

In A Marta le gusta el café, a Marta means roughly “to Marta” and identifies the person experiencing the liking.

Quick rule

For beginners, remember these four common patterns:

movement + a + place → Voy a Madrid.
a + person + gustar-type verb → A Marta le gusta.
verb + personal a + person → Veo a Marta.
ir a + infinitive → Voy a estudiar.

You will also use a before clock times: a las ocho.
