The compound tenses are formed by taking the auxiliary verb “haber” and adding a past participle (in the masculine form).
Therefore, the conditional perfect takes the future tense form of the verb “haber” and adds the past participle.
Here is “haber” in the conditional tense:
| singular | plural | |
|---|---|---|
| first person | habría | habríamos |
| second person | habrías | habríais |
| third person | habría | habrían |
Here is an example of “comer” conjugated in the conditional perfect. Note that the past participle of “comer” is comido.
yo habría comido
tú habrías comido
él/ella/usted habría comido
nosotros habríamos comido
vosotros habríais comido
ellos/ellas/ustedes habrían comido
