Lesson 15: Direct object pronouns — me, te, lo, la, nos, os, los, las

Part 1: What a direct object is

A direct object (complemento directo, CD) answers "what?" or "whom?" after the verb — the thing or person directly affected by the action.

Question	Example	The CD
¿Qué? (what?)	Compro el libro. — I'm buying the book.	el libro
¿A quién? (whom?)	Veo a María. — I see María.	a María
¿Qué?	Necesito agua. — I need water.	agua
¿A quién?	Llamo a mi madre. — I'm calling my mother.	a mi madre

Notice: in front of a person, Spanish adds the personal a — Veo a María, not Veo María. In front of a thing, no a. Full story on personal a comes in Lesson 16; for now, just register the marker.

Once the CD is obvious from context, Spanish replaces it with a pronoun:

— ¿Compras el libro? — Sí, lo compro. — ¿Ves a María? — Sí, la veo.

English does this too ("Yes, I'm buying it"). The difference is where the pronoun lands.

Part 2: The full table

Person	Singular	Plural
1st (me / us)	me	nos
2nd informal (you / you all)	te	os (Spain)
3rd masc. (him / them m.)	lo	los
3rd fem. (her / them f.)	la	las
Formal "you" (m. / f.)	lo / la	los / las

Key insight: me, te, nos, os are gender-neutral. lo / la / los / las agree in gender and number with the noun they replace. El libro → lo. La casa → la. Los libros → los. Las casas → las. English has just one "it" / one "them"; Spanish makes you pick.

Agreement in action

Replaced	Pronoun	Example	Replaced	Pronoun	Example
el coche (m. sg.)	lo	Lo compro.	los libros (m. pl.)	los	Los leo.
la casa (f. sg.)	la	La veo.	las llaves (f. pl.)	las	Las tengo.
a Pedro (m. sg.)	lo	Lo llamo.	a mis amigos (m. pl.)	los	Los veo.
a María (f. sg.)	la	La llamo.	a mis hermanas (f. pl.)	las	Las ayudo.

Regional note — leísmo: in Spain you'll often hear le instead of lo for a male human direct object — A Pedro le veo vs. A Pedro lo veo. The Royal Academy tolerates this single-person leísmo; Latin America uses lo / los uniformly. We teach the universal standard: lo for any masculine direct object — person or thing. Recognize le if you hear it; say lo and you'll be understood everywhere.

Part 3: Position — where the pronoun goes

This is THE rule of Lesson 15. Your English instinct is to put the pronoun after the verb. Spanish puts it before. Burn this in.

Rule 1: BEFORE the conjugated verb

In a simple statement, question, or negation, the pronoun sits directly before the conjugated verb, as a separate word.

Spanish	English	What matters
Lo veo.	I see him / it.	lo before veo
La compro.	I'm buying it.	la before compro
Nos llaman.	They're calling us.	nos before llaman
No lo conozco.	I don't know him.	no + pronoun + verb
¿Me ves?	Do you see me?	Same position in a question
Siempre te ayudo.	I always help you.	Adverbs don't break the bond

The trap: you want to say "Veo lo" because English says "I see him". You can't. The pronoun must come first: Lo veo. The pronoun and verb form an almost-single unit: lo-veo, la-compro, te-llamo. Only no can stand between them.

Rule 2: With infinitive or gerund — TWO equal options

When the verb is paired with another (auxiliary + infinitive, or estar + gerund), the pronoun has two legal positions, both correct, both natural:

Construction	Option A: BEFORE the auxiliary	Option B: ATTACHED to second verb
ir a + inf.	Lo voy a comprar.	Voy a comprarlo.
querer + inf.	Te quiero ver.	Quiero verte.
poder + inf.	Los puedo ayudar.	Puedo ayudarlos.
tener que + inf.	La tengo que llamar.	Tengo que llamarla.
estar + gerund	Lo estoy mirando.	Estoy mirándolo.

Spelling alert — the written accent: attach a pronoun to a gerund and you need an accent to keep the original stress: mirando → mirándolo (stress still on -RAN-). When attaching to a bare infinitive, no accent — the stress was already on the last syllable: comprarlo, verla, llamarte — clean.

Rule 3: With imperatives

In an affirmative command, the pronoun attaches to the end of the verb, forming one word. The added syllable would shift the natural stress, so a written accent locks the original stress: compra → cómpralo.

Affirmative — glued on	Negative — back in front
¡Cómpralo! — Buy it!	¡No lo compres! — Don't buy it!
¡Llámame! — Call me!	¡No me llames! — Don't call me!
¡Ayúdanos! — Help us!	¡No nos ayudes! — Don't help us!
¡Espérala! — Wait for her!	¡No la esperes! — Don't wait!

Imperatives get their own full lesson (L29). For now, just recognize the patterns.

Part 4: Lo neutro and personal a

Lo neutro — replacing a whole idea

Lo can also stand in for an entire sentence, idea, or fact — something with no gender. English uses "it" or "that" the same way.

Spanish	English
Lo sé. / No lo sé.	I know (it). / I don't know.
Lo siento.	I'm sorry. (fixed!)
Lo entiendo.	I understand (the situation).
Lo creo.	I believe it.
Te lo prometo.	I promise (you that).

Memorize: Lo siento is not "I feel something masculine." It's the fixed phrase "I'm sorry." Never la siento.

Lo + masc.-sg. adjective creates "the [adjective] thing": lo importante (what matters), lo bueno / lo malo, lo mejor / lo peor. Lo importante es estudiar. For now, just recognize it.

Personal a

Spanish puts the preposition a in front of a direct object that's a specific person:

No person (no a)	Person (with a)
Veo la casa.	Veo a María.
Compro el libro.	Espero a mi hermano.
Conozco Madrid.	Conozco a sus padres.

When you replace "person + a" with a pronoun, the a disappears: Veo a María → La veo. Espero a mi hermano → Lo espero. Conozco a tus padres → Los conozco. Full coverage in Lesson 16.
