recruter

French recruter came from recroître (to grow again), from Latin recrescere: re- (again) + crescere (to grow). The word entered French military vocabulary in the seventeenth century. After a battle thinned the ranks, the army needed to recroître — to grow again, to replenish itself with new soldiers. The recruits were the new growth. The metaphor was agricultural: war was the reaping, recruitment was the replanting.

Louis XIV's France industrialized recruitment. His war minister, the Marquis de Louvois, created a bureaucratic system for raising troops that replaced the feudal levy with organized conscription and voluntary enlistment. The word recruit entered English around 1640, initially meaning a newly enlisted soldier, then extending to mean the act of enlisting itself. The gardening metaphor was already invisible by the time English speakers used the word.

Recruitment evolved from royal prerogative to national obligation. The French levée en masse of 1793 — universal conscription — was a revolutionary innovation that changed the scale of warfare. Every citizen was potentially a recruit. The Napoleonic Wars, the American Civil War, and both World Wars all depended on mass recruitment. The word that meant 'a plant growing back' named the machinery that fed millions into industrialized war.

Modern recruitment has split into military and civilian meanings. HR departments recruit employees. Universities recruit students. Sports teams recruit athletes. The military still recruits soldiers. In every context, the word names the same process: finding new people to replenish an organization. The agricultural origin — growth after cutting — is perfectly accurate for institutions that constantly lose members and need to replace them.
