lynchpin

noun
Usage
What does lynchpin mean? Lynchpin is an alternate spelling of linchpin—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 the word 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 lynchpin is someone or something that keeps the wheels from falling off of an operation—they keep the whole thing working. Lynchpin is not related to the verb lynch. It is much less commonly used than linchpin. Example: Their point guard wasn’t their main scorer, but she was the lynchpin to the team’s success, and they started to lose a lot of games after she was injured.
Explanation
A lynchpin is a vitally important person or an essential element. You could say that a star player is the lynchpin of the team, or that technology is the lynchpin of the California economy. Without the lynchpin, a group or project just won't work, won't go as smoothly, or will be otherwise less successful. The lynchpin of many bands is a great lead singer, and the lynchpin of a bountiful vegetable garden is rich, healthy soil. This figurative meaning of lynchpin (which is also spelled linchpin) comes from the literal definition: a pin that keeps a wheel attached to an axle.
