In this post, you’ll learn the 12 main irregular Spanish past participles. This will allow you to conjugate any verb in the present, past, future or conditional perfect tenses.
In Spanish, the verb tenses that have a ‘perfect’ in their title allow you to form ideas like:
You will have…
He would have…

How to form regular Spanish past participles
We can categorise regular Spanish past participles into two groups: ‘ar‘ verbs and ‘er and ir‘ verbs.
To form past participles for regular ar verbs, you need to remove the ar and replace it with an ado. Here are some examples:
Pasar → Pasado.
Dejar → Dejado.
Tomar → Tomado.
To form past participles for regular er and ir verbs, you need to remove the er or ir and replace it with an ido. Some examples:
Deber → Debido.
Vivir → Vivido.
Permitir → Permitido.
Any Spanish verb that isn’t in the list below (or has a common stem from the list below) will have a regular past participle and can be formed with these two rules.

How to use the irregular Spanish past participles for verbs with common stems
One of the most forgiving aspects of Spanish verb conjugations happens with verbs that have common stems (called verbos compuestos). Verbs with common stems are made simpler by the fact they conjugated in the same way.
Whenever you see a verb from the above table with a prefix, you will now know how to conjugate it.
For example, take the verb hacer, then find any verb with a prefix. They will be conjugated as follows:
Hacer (to do) → Hecho.
Deshacer (to undo) → Deshecho.
Rehacer (to redo) → Rehecho.
Similarly, here are some examples with poner:
Poner (to put) → Puesto.
Suponer (to suppose) → Supuesto.
Disponer (to provide) → Dispuesto.
Proponer (to propose) → Propuesto.
And some examples with decir:
Decir (to say) → Dicho.
Desdecir (to deny) → Desdicho.
Contradecir (to contradict) → Contradicho.
