Questions & Answers about Me duele el trasero.
Because doler works like gustar.
In Spanish, the thing that hurts is the grammatical subject, and the person affected is shown with an indirect object pronoun.
So in Me duele el trasero:
- me = to me
- duele = hurts
- el trasero = the backside / butt
Literally, it is closer to:
- The backside hurts to me
Natural English changes that to:
- My butt hurts
- My backside hurts
You normally do not say yo duelo to mean I hurt in this sense.
Me is an indirect object pronoun meaning to me.
It shows who is experiencing the pain.
Other forms would be:
- Te duele el trasero = Your backside hurts
- Le duele el trasero = His/her backside hurts
- Nos duele el trasero = Our backside hurts
So me does not mean my here. It means to me.
