/ˈbɔɪ/

Etymology

From Middle English boy, boye, from Middle Dutch boeye (“float, buoy”), from Old French boue (“piece of wood or cork that floats above an anchor to indicate where it is anchored”) (modern French bouée), ultimately from Frankish *baukn (“beacon”). Doublet of beacon.
Alternatively, and perhaps less likely (due to the unexplained shift in meaning), from Middle Dutch boeye (“shackle, fetter”), from Old French buie (“fetter, chain”), from Latin boia (“a (leather) collar, band, fetter”), from Ancient Greek βόεος (bóeos), βόειος (bóeios, “of ox-hide”), from βοῦς (boûs, “ox”), from Proto-Indo-European *gʷṓws (“cow”).
