"Where are your brother's clothes?"
Translation:¿Dónde está la ropa de tu hermano?
Why is '¿Dónde está la ropa de su hermano?' marked as incorrect? Couldn't it be the case that I speak to the other person using 'usted' etc.?
It was accepted just now for me. FWher, you were right su means your when you use usted.
the difference is, i think, that está is used for something temporary (like place etc.) and es for something that stays the same. correct me if i'm wrong
