troop

Attested in English since 1545, from French troupe (back-formation of troupeau, diminutive of Medieval Latin troppus "flock") and Middle French trouppe (from Old French trope (“band, company, troop”)), both of Germanic origin from Frankish *þorp (“assembly, gathering”), from Proto-Germanic *þurpą (“village, land, estate”), from Proto-Indo-European *treb- (“dwelling, settlement”).

Doublet of troupe, and possibly also of thorp and dorp. Cognate with German Dorf (“village”).
