The word "enforcer" combines "enforce" (from Old French enforcier, "to strengthen, compel," derived from Latin in- "in" + fortis "strong") with the agent suffix "-er." Originally tied to physical or legal compulsion, it later expanded to roles in sports and technology. The morphemes reflect a clear progression: strength (fortis) applied (in-) by an agent (-er).
