Just like the verb piacere in the present tense, piacere in other tenses takes the third-person singular and plural.
Piacere is conjugated with essere in the passato prossimo, so the past participle agrees in gender and number with the subject.
Remember that the subject is the person, place, or thing that is liked and it often follows piacere.
Here are the points to keep in mind :
- Piacere takes essere (to be) in compound tenses.
- Piacere’s past participle is piaciuto.
- Piaciuto has to agree with what was liked, not with who liked it.
Mi piace la musica (I like music)
Mi è piaciuta la musica (I liked the music)
Ti piacciono gli spaghetti? (Do you like spaghetti?)
Ti sono piaciuti gli spaghetti? (Did you like spaghetti?)
When the subject is an action (an infinitive verb), piacere is in the third person singular and the participle ends in –o.
Mi piace cucinare la lasagna (I like to cook lasagna)
Mi è piaciuto cucinare la lasagna (I liked to cook lasagna)
