Usage
What does linchpin mean? A linchpin is the person or thing that serves as the essential element in a complicated or delicate system or structure—the one that holds everything together.This sense of linchpin is based on its original, literal meaning: an actual pin used to attach a wheel to the axle of a carriage or wagon to keep the wheel from falling off. It’s a good metaphor: a linchpin is someone or something that keeps the wheels from falling off of an operation—they keep the whole thing working. It can also be spelled lynchpin.Example: Their point guard wasn’t their main scorer, but she was the linchpin to the team’s success, and they started to lose a lot of games after she was injured.
