If I call you up at 7:30pm to invite you to have dinner at restaurant, you might say to me, "Oh, Debi, I have eaten dinner already!"
I may respond by suggesting instead that we rent the movie Titanic, to which you may reply, "Debbie, I have seen Titanic five times already."
I may try again suggesting we go out to our favorite coffee house, to which you say, "Oh, no! Debi, I have given up caffeine!"
At this point, I might say, "I have had enough!"
All of these verb constructions are in the Present Perfect Tense.
While you understand that these actions have taken place in the past (they are completed actions), they still have a sense of immediacy: They have taken place, but recently.
To form the Present Perfect in English, we use a conjugation of to Have and a Past Participle. Past Participles in English are words like "eaten," "written," "walked," and "rung." We use them with to Have in the sense of to "have done/finished something."
- "I have finished my project."
- "I have seen that man before."
- "I have had enough examples."
There is a wide variety in the construction of past participles in English. We say "I have walked," "I have sung," "I have written," and "I have gone." There are a lot of irregulars in English. Who hasn't wrestled with "swam" vs. "swum" or "swelled" vs. "swollen"?
To form the Present Perfect In Spanish, we conjugate the verb Haber in the Present Tense. Haber means "to Have".
We put the form of Haber together with a Past Participle in the same manner that we put Estar together with a Present Participle to form the Present Progressive.
Here are the conjugations for Haber:
|Yo||Tú||él, ella, ud.||nosotros||ellos, ellas, uds.|
To form Past Participles in Spanish, we simply add -ado to the stem of -Ar verbs and -ido to the stem of -Er and -Ir verbs.
For example, let's look at an -Ar verb: Estudiar
- Estudi- ar (we remove the infinitive ending)
- Estudi- (we are left with our root)
- Estudi + ado (we add the -Ar ending ado)
- Yo he estudiado toda la noche. (we add a conjugation of Haber to form a sentence in the Present Perfect)
With -Er and -Ir verbs, drop the -er and -ir, and
For example, let's look at Perder:
- Perder --> er
- Perd + ido
- Yo he perdido mis llaves.
In the Perfect tenses, Past Participles are being used as part of a compound verb. So the endings stay the same in the same way that Present Participles remained unchanged no matter the gender or number of people involved:
- Tomás ha terminado la tarea.
- Alicia ha terminado la tarea.
- Los estudiantes han terminado la tarea.
- Nosotros hemos terminado la tarea.
