Questions & Answers about Ya he terminado la reseña, pero todavía no he revisado la bibliografía.

Why does the sentence use he terminado and he revisado instead of a simple past tense like terminé or revisé?

In Spain Spanish, the present perfect (he terminado, he revisado) is very commonly used for actions connected to the present, especially when talking about something that has happened today, recently, or in a time period that still feels current.

So this sentence suggests:

• I have already finished the review
• but I still haven’t checked the bibliography

That feels relevant right now.

In many parts of Latin America, speakers might more often use the simple past here:

• Ya terminé la reseña, pero todavía no revisé la bibliografía.

Both are grammatical, but he terminado / he revisado is especially natural in Spain.

How is the present perfect formed in Spanish?
