Etymology Origin:
The word "muster" originates from Latin monstrare ("to show"), passing through Old French muster as a military term for assembling troops for inspection. Over time, it broadened to mean any formal gathering or the act of summoning resources (e.g., "muster courage"). The logic ties to the idea of "showing up" or "demonstrating readiness."
