executor

The word 'executor' has a clear narrative of agency and completion. It originates from the Latin verb exsequi, meaning "to follow out, to carry out, to accomplish," which is itself a compound of ex- ("out") and sequi ("to follow"). This literal sense of "following a task through to its conclusion" passed into Anglo-Norman and Middle English as 'executour,' specifically referring to one who follows out the instructions of a deceased person. The modern spelling and dual meanings—both legal (a will's executor) and general (one who executes a plan)—preserve this core idea of an agent who ensures a set course is thoroughly carried out.
