escape

Etymology

From Middle English escapen, from Anglo-Norman and Old Northern French escaper ( = Old French eschaper, modern French échapper), from Vulgar Latin *excappāre, literally "get out of one's cape, leave a pursuer with just one's cape," from Latin ex- (“out”) + Late Latin cappa (“cape, cloak”). Cognate with escapade.
