The name of this tense in Spanish is: "Condicional compuesto".
The construction is:
[SUBJECT] + ['haber' in simple conditional (habría)] + [PARTICIPLE]
Con más tiempo, habría terminado el examén
With more time, I would have finished the test
We remember the conjugation of the auxiliary 'haber' in the simple future tense:
| Conjugation | Meaning |
|---|---|
| yo habría | -- |
| tú habrías | -- |
| él habría | -- |
| nosotros habríamos | -- |
| vosotros habríais | -- |
| ellos habrían | -- |
To construct the interrogation, change only the position of the subject:
| Affirmation | Interrogation |
|---|---|
| tú habrías comenzado you would have started | ¿habrías comenzado (tú)? would you have started? |
To build the negation, add simply the adverb "no" before the verb:
| Affirmation | Negation |
|---|---|
| yo habría dormido I would have slept | yo no habría dormido I would not have slept |
