Questions about Spanish, please explain it in details, thanks a lot!
1. Dame la-tu mano. ¡Se han dejado el-su eequipaje en el aeropuerto!
In these two sentences, which ones should I use, la-tu, el-su? And why? For me,I think both could be used, but not according to my exercise book, and it didn't give me explainations.
2. Qué guapa está María, lo bien que le sienta ese vestido.
Why que is used here? Could it be omitted?
