The phrase "pass muster" originated in the military, specifically in reference to the process of inspecting and evaluating soldiers. In this context, "muster" refers to the assembly or gathering of troops for inspection. The term "muster" can be traced back to the Old French word "monstrer", meaning "to show, to display". This Old French word is derived from the Latin word "monstrare", which has the same meaning. Over time, "muster" evolved to specifically refer to the gathering of troops for inspection and assessment.
