Coercion in linguistics means that someone is using language to make you do something you may not really want to do. For example, if someone says "You should come to my party tonight, everyone will be there!" even though you're tired and don't want to go, they're trying to coerce you into going. It's like when your mom says "Eat your vegetables because they're good for you" even though you don't really want to eat them. Coercion can sometimes be sneaky and you might not even realize someone is doing it. That's why it's important to always think for yourself and make your own choices.
