recruit: [17] Etymologically, a recruit is something that ‘grows again’. The word’s ultimate ancestor is Latin recrēscere ‘regrow’, a compound verb formed from the prefix re- ‘again’ and crēscere ‘grow’ (source of English crescent, increase, etc). This passed into French as recroître, whose feminine past participle in the standard language was recrue. In the dialect of northeastern France, however, it was recrute, and it was this, used as a noun meaning ‘new growth’, hence ‘reinforcement of troops’, that gave English recruit.

"military reinforcement, one of a newly raised body of troops," 1640s, from recruit (v)., replacing earlier recrew, recrue; or from obsolete French recrute, alteration of recreue "a supply," recrue "a levy of troops" (late 16c.), Picardy or Hainault dialect variant of recrue "a levy, a recruit," literally "new growth," from Old French recreu (12c.), past participle of recreistre "grow or increase again," from re- "again" (see re-) + creistre "to grow," from Latin crescere "to grow" (see crescent). "The French word first appeared in literary use in gazettes published in Holland, and was disapproved of by French writers in the latter part of the 17th c." [OED]. The French word also is the source of Dutch recruut, German Recrut, Swedish rekryt.
