Introduction: the present perfect
The present perfect (pretérito perfecto) is the Spanish "I have done" tense. This week you will use it for life experiences: things you have or haven't done at some point in your life, without saying when.
The formula is haber (conjugated) + past participle. Only haber changes for each person; the past participle stays the same.
| Person | Singular | Plural |
|---|---|---|
| 1st person | (yo) he | (nosotros/as) hemos |
| 2nd person | (tú) has | (vosotros/as) habéis |
| 3rd person | (él/ella/usted) ha | (ellos/ellas/ustedes) han |
Examples
Nothing goes between haber and the participle. Negatives and object pronouns go before haber: "No he comido", "Lo he visto" (never "He no comido" or "He lo visto").
