"Set aside" means to keep something separate for later use or consideration. It's like when you put money into a savings account instead of spending it right away. Or when you save time for a special activity instead of doing it immediately. You might set aside clothes you want to donate or books you want to read later. It's about intentionally keeping something for a specific purpose or time. So, "setting aside" means to reserve or save something instead of using it immediately, often for later use or consideration.
