KK: /ˈlɪnʧpɪn/
A crucial part or element that holds things together or makes them work effectively.
The manager is the linchpin of the team, ensuring everyone works well together.
Linchpin → The word 'linchpin' originates from Middle English 'lynchpin', which comes from 'lynch' (meaning to fasten) and 'pin' (meaning a small cylindrical object used to hold things together). A linchpin is a pin that fastens or secures a wheel to an axle, thus holding things together.
Think of a 'pin' that 'fastens' things together — that's what a linchpin does, it secures and holds everything in place.
