In Spanish, a small group of verbs has a "dual personality." They have a regular past participle used to build compound verbs, and a separate, irregular form used purely as an adjective.
The verbal form (with haber)
When forming perfect tenses (like "has printed" or "has provided") with the auxiliary verb haber, use the regular past participle ending in -ado or -ido. In this role, the participle is strictly part of the verb and never changes its gender or number.
| The roaster has printed the acidity level on the box. | El tostador ha imprimido el nivel de acidez en la caja. |
| The barista has provided us with a new coffee maker. | El barista nos ha proveído una cafetera nueva. |
The adjectival form
When describing a noun's state—either directly next to the noun or after verbs like estar—use the irregular adjectival form. Because it acts as a normal adjective, its ending must change to match the noun's gender and number (e.g., -o, -a, -os, -as).
| Put the filter in the coffee maker and read the printed recipe. | Pon el filtro en la cafetera y lee la receta impresa. |
| The store uses the scale provided by the roaster. | La tienda usa la balanza provista por el tostador. |
Common verbs with adjectival forms
Several everyday verbs follow this exact pattern. They use a regular participle for actions with haber, but rely on a shortened, irregular adjective to describe the resulting state.
Common pairs include:
- limpiar (to clean): limpiado (action) / limpio (state)
- secar (to dry): secado (action) / seco (state)
- llenar (to fill): llenado (action) / lleno (state)
- vaciar (to empty): vaciado (action) / vacío (state)
Notice how both forms appear together in these examples to highlight the difference between the action that was performed and the resulting state:
| The grinder is clean because I have cleaned each piece to maintain the ratio. | El molinillo está limpio porque he limpiado cada pieza para mantener la proporción. |
| The farmer has dried the beans for the roast, and now they are dry. | El campesino ha secado los granos para el tueste, y ahora están secos. |
| We have emptied the cup to measure the correct ratio, so it is already empty. | Hemos vaciado la taza para medir la proporción correcta, así que ya está vacía. |
