Learn Spanish (Latin America): Necesito doblarla y guardarla.

When you use an infinitive (a basic, unconjugated verb ending in -ar, -er, or -ir), you can attach object pronouns like la directly to the end of it. That is why doblar (to fold) becomes doblarla (to fold it).

Could I move the la to the front of the sentence instead?

Yes! When a conjugated verb like necesito is followed by an infinitive, you have two choices for where the pronoun goes. You can attach it to the end of the infinitive (necesito doblarla), or you can place it right before the conjugated verb (la necesito doblar). Both are common and perfectly correct.

Because there are two verbs linked by y (and), do I have to use la twice?

If you attach the pronoun to the end of the verbs, doing it to both (doblarla y guardarla) sounds very natural and clear. However, if you choose the other option and move the pronoun to the front of the sentence, you only need to say it once for both actions: La necesito doblar y guardar.

Why is "it" translated as la here instead of lo?
