The word "performance" originates from the Middle English "performen," derived from Anglo-French "parfournir" (to complete or accomplish). The root "perform" combines "per-" (thoroughly) and "form" (to shape or execute), reflecting the idea of fully executing a task. The suffix "-ance" transforms the verb into a noun, denoting the act or result of performing. Over time, its meaning expanded to include artistic presentations and measurable efficiency.
