Questions & Answers about ¿Puedo sentarme aquí?
Because sentarse is a reflexive verb in Spanish.
- sentar usually means to seat someone/something
- sentarse means to sit down
In ¿Puedo sentarme aquí?, the me means myself, so sentarme literally works like to sit myself down.
After a conjugated verb like puedo, Spanish often attaches the reflexive pronoun to the infinitive:
- Puedo sentarme aquí
- also possible: Me puedo sentar aquí
Both are correct.
Puedo is the first person singular form of poder, which means can / to be able to.
So:
- puedo = I can
- ¿Puedo...? = Can I...?
It is a very common way to ask permission politely in Spanish.
