Questions & Answers about Quiero entregar el informe a la profesora antes de la reunión.

Why is it quiero entregar and not quiero entrega?

In Spanish, when one verb is followed by another verb, the second one normally stays in the infinitive form.

• Quiero entregar = I want to hand in / deliver
  
  • quiero → conjugated (1st person singular, present)
  • entregar → infinitive

You never conjugate both verbs in this structure.
Using quiero entrega would be like saying “I want deliver” in English—ungrammatical.

Can I say Yo quiero entregar el informe…? Is yo necessary?

You can say it, but it’s usually not necessary.

• Quiero entregar el informe…
• Yo quiero entregar el informe… (more emphasis on I)

In Spanish, the verb ending (-o in quiero) already tells you the subject is yo, so the pronoun is often dropped unless you want contrast or emphasis:

• Yo quiero entregar el informe, pero ellos no quieren.

Why use entregar instead of just dar?
