The Conditional Perfect — El Condicional Compuesto
In English: would have + past participle
Yo habría terminado → I would have finished
How to Form It · Structure
Auxiliary
HABER
habría · habrías · habría…
Main verb
Participio
-ado · -ido · irregular
Yo habría terminado antes.
→ I would have finished earlier.
haber and the participle must always stay together — you cannot separate them with other words.
Step 1 · The Auxiliary Verb
This is your helping verb in the Simple Conditional. Memorize this table — it never changes.
Notice that Yo and Él/Ella/Usted share the same form: habría. Context tells them apart!
Step 2 · Past Participle
Drop the verb ending and add the correct participle suffix — just two rules to remember.
hablar → hablado
Yo habría hablado con él.
→ I would have spoken with him.
comer → comido
vivir → vivido
Ella habría comido más.
→ She would have eaten more.
The pattern never changes: find the stem → add -ado or -ido. If you can conjugate the present tense, you can build any participle!
Step 2 continued · Irregular Participles
These 5 verbs don't follow the -ado/-ido rule. You must know them by heart.
hacer
↓
hecho
decir
↓
dicho
escribir
↓
escrito
abrir
↓
abierto
ver
↓
visto
Yo habría escrito el correo.
→ I would have written the email.
Notice that many irregular participles end in -to (hecho, dicho, escrito, abierto, visto). That pattern is your clue!
Use #1 of 3 · Unrealized Actions
Use the Conditional Perfect to say something would have happened, then use pero to explain what stopped it.
Yo habría ido con ellos, pero no me invitaron.
→ I would have gone with them, but they didn't invite me.
Ella habría llamado, pero no tenía su número.
→ She would have called, but she didn't have his number.
When you see pero in the second clause, that's your signal — the Conditional Perfect belongs in the first clause.
Use #2 of 3 · Two Sub-meanings
English: "must have" — guessing about something that already happened.
Habrían sido las diez.
→ It must have been ten o'clock.
English: "could have / should have" — expressing that someone failed to do something they should have.
Habrías podido avisarme.
→ You could have warned me.
Speculation is neutral guessing ("must have been…"). Criticism implies the person failed to do something they should have.
Use #3 of 3 · Type 3 Conditional
If-clause (Si)
Si + hubiera + participio
Result clause
habría + participio
Si hubieras estudiado, habrías aprobado.
→ If you had studied, you would have passed.
⚠ Never use conditional after "si"!
Si habría tenido tiempo… ✗
Si hubiera tenido tiempo… ✓
terminaría = "I would finish" (simple conditional) · habría terminado = "I would have finished" (conditional perfect)
