¿Quieres acompañarme a la biblioteca?

In Spanish, the subject pronoun is often omitted because the verb ending already shows who the subject is.

• quiero = I want
• quieres = you want
• quiere = he/she/you (formal) wants

So ¿Quieres acompañarme a la biblioteca? already clearly means Do you want... ? addressed to you.

You could say ¿Tú quieres acompañarme a la biblioteca?, but adding tú usually gives extra emphasis, contrast, or insistence.

Because it is the infinitive acompañar plus the object pronoun me attached to the end:

• acompañar = to accompany
• me = me

So:

• acompañarme = to accompany me

In Spanish, object pronouns can attach to an infinitive. This is very common.

Yes. ¿Me quieres acompañar a la biblioteca? and ¿Quieres acompañarme a la biblioteca? are both correct and mean essentially the same thing.

Spanish often allows the object pronoun either:

• before the conjugated verb: me quieres acompañar
• attached to the infinitive: quieres acompañarme

Both are natural.

Here acompañar means to come/go with someone or to accompany someone.

So this sentence is a natural way to ask:

• Do you want to come with me to the library?
• literally, Do you want to accompany me to the library?

In everyday English, come with me sounds more natural, but in Spanish acompañar is a very normal verb in this kind of situation.

That a is the preposition meaning to.

• a la biblioteca = to the library

It shows the destination.

So:

• acompañarme a la biblioteca = accompany me to the library

This is not the personal a used before people; it is simply the a of movement/destination.

Because biblioteca is feminine:

• la biblioteca = the library

The contraction al only happens with a + el:

• a + el parque = al parque

But with la, there is no contraction:

• a + la biblioteca = a la biblioteca

Spanish does not use an extra helping verb like English do to make most questions.

English:

• Do you want to come with me?

Spanish:

• ¿Quieres acompañarme...?

Spanish usually forms questions through:

1. intonation in speech
2. question marks in writing
3. context

There is no need for a separate word like do here.

Because Spanish does not usually require subject-verb inversion the way English sometimes does.

English changes:

• You want...
• Do you want...?

Spanish can keep the same basic structure:

• Quieres...
• ¿Quieres...?

The question marks and spoken intonation show that it is a question.

Spanish uses an opening question mark ¿ and a closing question mark ? to clearly show where the question begins and ends.

So:

• ¿Quieres acompañarme a la biblioteca?

This is standard spelling in Spanish.

Use usted form instead of tú form:

• ¿Quiere acompañarme a la biblioteca?

Here:

• quiere = you want (formal)

This is what you would use with someone you address as usted, for example in a more polite or formal situation.

In Spain, for informal plural you, use vosotros/vosotras:

• ¿Queréis acompañarme a la biblioteca?

For formal plural, use ustedes:

• ¿Quieren acompañarme a la biblioteca?

So in Spain:

• quieres = you singular informal
• queréis = you plural informal
• quiere = you singular formal
• quieren = you plural formal

Spanish often uses the definite article more than English does.

So a la biblioteca is the normal way to say to the library.

Saying just a biblioteca would be incorrect here.

Yes, it is correct and natural. It sounds a little like Would you like to come with me to the library?

Depending on tone and context, a Spaniard might also say something like:

• ¿Vienes conmigo a la biblioteca? = Are you coming with me to the library?
• ¿Te apetece acompañarme a la biblioteca? = Do you feel like coming with me to the library?

But ¿Quieres acompañarme a la biblioteca? is perfectly good Spanish.

The ñ is pronounced like the ny sound in canyon.

So acompañarme is roughly:

• a-kom-pa-NYAR-me

The stress falls on ñar because the infinitive is acompañar.

Also remember that the written accent in acompañar stays important for pronunciation when the pronoun is attached:

• acompañar
• acompañarme

Sometimes acompañar can mean escort in certain contexts, but in everyday situations like this one, it usually just means go/come with me.

With a la biblioteca, the meaning is very natural:

• Would you like to come with me to the library?

So learners should not worry too much about it sounding overly formal or dramatic here.
