Questions & Answers about La llamaré más tarde.
What does the pronoun la refer to here?
Why is the pronoun placed before the verb?
With a conjugated (finite) verb like llamaré, object pronouns go before it: La llamaré. You only attach pronouns to infinitives, gerunds, and affirmative commands: llamarla, estoy llamándola, llámala.
So can I say “Llamaréla”?
No. You can’t attach a pronoun to a finite future form. Say La llamaré; or use an infinitive: Voy a llamarla / La voy a llamar.
Is there a nuance between La llamaré and La voy a llamar / Voy a llamarla?
All express an intention. In everyday Spain, voy a + infinitive and even the present (La llamo luego) are more common for near-future plans; La llamaré often sounds a bit more formal or like a promise/commitment.
How would I say “I will call him later” in Spain?
