Etymology

Origin of buy

First recorded before 1000; Middle English byen, variant of byggen, buggen, Old English bycgan; cognate with Old Saxon buggjan, Gothic bugjan “to buy,” Old Norse byggja “to lend, rent”

Explanation

When you buy something, you pay money in order to own or obtain it. You might buy your mom a big bouquet of flowers for her birthday. When you buy furniture, food, a car, or candy, you purchase it, exchanging a certain amount of money for it, and when you call something "a buy" or "a steal," it's a real bargain. When you say, "She said she won the lottery, but I don't buy it," you mean that you don't accept that fact as the truth. Even more colloquially, to buy it can also mean "to be killed."
