As a verb, “check” means to look at something carefully to make sure it is correct, safe, or in good condition. As a noun, it can mean a mark to show something has been done, a written order to pay money from a bank account, or the bill at a restaurant.
“Check” comes from Old French “eschec,” from Persian and Arabic words for “king” used in the game of chess. The idea of stopping the king in chess grew into the idea of stopping, limiting, or verifying things in everyday life.
