In a later lesson, we're taught, "O pai dele é promotor," where the pronoun follows the noun. Here we're taught, "A sua irmã é minha noiva," where the pronoun precedes the noun. Is dele/dela always after the noun, and is sua/seu,tua, teu always before, please?
But how do you know when to use "the" in front of a word like that? In English, we would never say "the" before the word "your" so I'm just wondering if you can always say "the" before "Your" in Portuguese if you feel like it or if it depends on the noun that comes after.
