Questions & Answers about Et fa mal el braç?
Et is the unstressed object pronoun meaning to you.
So the structure is roughly:
- et = to you
- fa mal = hurts / causes pain
- el braç = the arm
A very literal way to think of the sentence is:
Does the arm hurt to you?
That is not natural English, but it helps explain the Catalan structure.
Because tu is a subject pronoun (you), while et is an object pronoun (to you).
In this sentence, you are not the grammatical subject. The thing doing the hurting is el braç.
So:
- tu = you as the subject
- et = you / to you as an object
Catalan uses the object pronoun here because the idea is literally closer to the arm hurts to you than to you hurt the arm.
