Answer :
In the sentence "Linda quiere comprar patines para su hermano," the underlined word "patines" means "skates."
Here's a breakdown to explain it further:
1. "Linda" is a name, referring to a person.
2. "Quiere" means "wants" or "desires."
3. "Comprar" means "to buy" or "to purchase."
4. "Para" means "for" or "to."
5. "Su" means "his" or "her."
6. "Hermano" means "brother."
Therefore, "patines" refers to "skates" in this context. Linda wants to buy skates for her brother.
