"Linchpin, sometimes spelled lynchpin, literally refers to a locking pin inserted crosswise, as at the end of an axle or shaft. In figurative use, linchpin refers to a person or thing that serves to hold together parts or elements that exist or function as a unit; such a linchpin is often understood as the most important part of a complex situation or system."
