Questions & Answers about Mi hermana vuelve a su cuarto tranquilo.
Why is the verb vuelve spelled with a "ue" instead of an "o"?
Vuelve comes from the verb volver (to return). It is a stem-changing verb, meaning the o in the middle changes to ue for most forms in the present tense. Since mi hermana (my sister) is a "she," we use the third-person singular form, making it vuelve instead of "volve."
Why do we need the word a before su cuarto?
The word a means "to." Just like in English, when someone goes or returns to a destination, you need a preposition to connect the verb to the place. So, vuelve a means "returns to."
I learned that su means "your." Why does it mean "her" in this sentence?
Why does tranquilo come after cuarto?
