Chapter 49 · B1
Core Prepositions: A, De, En, Con
Might help first: Ch. 3 — Los artículos (Definite & Indefinite), Ch. 13 — Indirect Object Pronouns, Ch. 42 — The Infinitive: Forms & Functions (a suggestion, never a requirement)
A, de, en, and con are the four prepositions you’ll reach for more than any other in Spanish — small words, but each one carries a cluster of distinct jobs that doesn’t map onto a single English preposition. Chapter 48 already handled por and para, the pair whose entire teachable content is the contrast between them; these four are a different kind of chapter — each has its own independent core meaning, and each earns its place here on sheer frequency and range. This chapter builds each preposition’s core sense from the ground up, then covers two genuinely distinct grammar points that ride on top of them: personal a, the marker that appears before a specific human direct object with no English word to translate it, and the long list of common verbs that simply come bundled with one fixed preposition, learned verb by verb.
Core Pattern: The Four Prepositions’ Core Meanings
Each of the four does several jobs, but every job traces back to one central idea. Start with that central idea, and the extensions later in this chapter read as natural growth rather than a random pile of uses.
A: Direction, a Point in Time, and the Indirect Object
A1At its core, a marks movement toward a destination or arrival at one specific point — in space or in time.
Voy a Barcelona este fin de semana.
I'm going to Barcelona this weekend.
La clase empieza a las nueve.
Class starts at nine.
A also marks the indirect object — the person a verb’s action is done to or for — which is why you’ll routinely see it doubled up with an indirect object pronoun (Chapter 13 covers that pairing in full):
Le di el regalo a mi madre.
I gave the gift to my mother.
A has one more job — marking certain direct objects — substantial enough to earn its own full section later in this chapter.
De: Origin, Possession, and Material
A1De marks where something comes from, who it belongs to, or what it’s made of — three senses that share one underlying idea: de points backward, to a source.
Soy de los Estados Unidos.
I'm from the United States.
Es el coche de mi hermano.
It's my brother's car.
Quiero un anillo de oro.
I want a gold ring.
En: Location, Transport, and a Span of Time
A1En marks being inside or at a location — and, a genuine contrast with English, it covers both “in” and “on” depending on context, since Spanish doesn’t draw the same line English does:
Los libros están en la mesa.
The books are on the table.
Vivo en Sevilla.
I live in Seville.
En also marks the means of transport used to get somewhere:
Vamos en tren, no en coche.
We're going by train, not by car.
And en marks a period of time something happens within, rather than one specific point (a’s job):
Nací en agosto.
I was born in August.
Terminé el examen en una hora.
I finished the exam within an hour.
Con: Accompaniment, Instrument, and Manner
A1+Con marks who or what accompanies an action — a person you’re with, a tool you use, or the manner something is done in — three variations on one “together with” idea.
Voy al cine con mis amigos.
I'm going to the movies with my friends.
Corto el pan con un cuchillo.
I cut the bread with a knife.
Habla con cuidado sobre ese tema.
Speak carefully about that topic.
Building Out: Contraction and the Verbs These Prepositions Govern
Contraction: al and del
A2Chapter 3 already covers this in full as part of the article system — it’s really a fact about el more than about a or de individually — but it’s worth a quick reminder here, since a and de are exactly the two prepositions involved. Whenever a or de is immediately followed by the article el, the two words always fuse: a + el → al, de + el → del.
Vamos al parque después del trabajo.
We're going to the park after work.
Verbs That Take A, De, En, or Con Before a Noun or Pronoun
B1A large number of common Spanish verbs come permanently bundled with one specific preposition — not because the meaning demands it, but simply because that’s the preposition Spanish fixed on for that verb, the way English fixes “depend ON” and “consist OF” rather than any other choice. Chapter 42 already built a list of this same kind, scoped specifically to verbs that link to a following infinitive (empezar A trabajar, dejar DE fumar, soñar CON viajar). Many of those very same verbs also govern a noun or pronoun object with that identical preposition — soñar con ese viaje works exactly like soñar con viajar, just with a thing instead of an action on the other side. Rather than repeat Chapter 42’s list, what follows is scoped to the noun/pronoun-object half: verbs whose defining relationship is to a person or thing, not to a following action. Where a verb below also commonly takes an infinitive with that same preposition, that pairing is Chapter 42’s territory.
- a — asistir a (to attend), jugar a (to play [a game/sport]), parecerse a (to resemble), acercarse a (to approach), oler a (to smell like), saber a (to taste like), renunciar a (to give up/resign from)
- de — depender de (to depend on), enamorarse de (to fall in love with), despedirse de (to say goodbye to), quejarse de (to complain about), fiarse de (to trust), carecer de (to lack), constar de (to consist of/be made up of)
- en — pensar en (to think about), confiar en (to trust), fijarse en (to notice), influir en (to influence), convertirse en (to turn into/become), especializarse en (to specialize in)
- con — soñar con (to dream of), contar con (to count on), casarse con (to marry), encontrarse con (to run into), enfadarse con (to get angry with), comparar con (to compare to/with)
Este trabajo depende mucho de la suerte.
This job depends a lot on luck.
¿Te acuerdas de aquel verano? Todavía sueño con él.
Do you remember that summer? I still dream about it.
Pienso mucho en ti estos días.
I think about you a lot these days.
Nuance, Exceptions & Contrast: Personal A
Every use of a so far has mapped onto something English also expresses, one way or another — direction, a time point, an indirect object marker of some kind. Personal a is different: it’s a use of a with no English equivalent whatsoever, a small word inserted purely to signal something about the direct object itself. It trips up English speakers not because the rule is complicated, but because English has nothing to translate it with — it simply vanishes in the English sentence and has to be supplied from the Spanish grammar alone.
Personal A: Marking a Specific, Animate Direct Object
B1When the direct object of a verb is a specific, identifiable person — or a cherished pet, treated the same way — Spanish inserts a immediately before it. It isn’t a preposition meaning “to” here; it’s purely a marker flagging “the noun that follows is an animate, specific direct object, not the subject.”
Compare that to an inanimate direct object, which never takes personal a:
Veo María, with no a at all, is simply ungrammatical here — not informal, not a minor slip, genuinely wrong, the same way a missing required word would be. The logic isn’t really “is this a person” in isolation; it’s animacy plus specificity together. A specific, identifiable human or beloved animal as a direct object needs the marker; an inanimate thing never does, no matter how definite it is.
Quiero mucho a mi perro.
I love my dog a lot.
¿Conoces a Marta?
Do you know Marta?
¿Conoces bien Madrid?
Do you know Madrid well?
When Personal A Is Dropped or Optional
B2Two situations soften the rule above. First, tener almost always drops personal a even before a human direct object, when it expresses simple possession or relationship rather than physically holding or locating someone:
Tengo tres hermanos.
I have three brothers.
But once tener shifts to mean physically keeping or locating a specific person somewhere, personal a comes back:
Tengo a mi hijo en el hospital.
I have my son in the hospital [right now].
Second, when the direct object is a person but genuinely non-specific — any member of a category, not one particular individual in mind — personal a is often dropped, the same way the indefinite article gets dropped for unspecified quantities (Chapter 3):
Busco un médico que hable inglés.
I'm looking for a doctor who speaks English.
Personal A with Indefinite Pronouns, and Telling It Apart from the Indirect-Object A
B1The indefinite pronouns alguien, nadie, and quién always count as specific-enough people for this rule, even though they don’t name anyone in particular — treat them as automatically triggering personal a whenever they’re a direct object:
No veo a nadie en la calle.
I don't see anyone in the street.
¿A quién buscáis?
Who are you all looking for?
One more thing worth separating cleanly: personal a and the indirect-object a (Chapter 13) are two different jobs wearing the identical word. A single sentence can use both at once, marking two different objects:
Le presenté a mi hermano a mi jefe.
I introduced my brother to my boss.
Bringing It Together
Faced with a, de, en, or con, start from each one’s core sense — direction/time-point/indirect-object for a, origin/possession/material for de, location/transport/time-span for en, accompaniment/instrument/manner for con — and most everyday uses fall out naturally from there. Two things don’t fall out of core meaning alone and simply have to be learned as their own facts: which preposition a specific verb happens to be bundled with (memorize verb by verb, using the reference list above), and personal a, which isn’t really about meaning at all — it’s a marker that appears whenever a direct object is a specific, animate being, with no English word to translate it.
Conozco a la mujer de mi vecino: vive en Sevilla, viaja siempre con su hermana, y se parece mucho a su madre.
I know my neighbor's wife: she lives in Seville, she always travels with her sister, and she looks a lot like her mother.
