- "vehicle for carrying a load," c. 1300, barewe, probably from an unrecorded Old English *bearwe "basket, barrow," from beran "to bear, to carry" (see bear (v.)). The original had no wheel and required two persons to carry it.
- barrow (n.2)
- "mound," Old English beorg (West Saxon), berg (Anglian) "barrow, mountain, hill, mound," from Proto-Germanic *bergaz (source also of Old Saxon, Old Frisian, Old High German berg "mountain," Old North bjarg "rock"), from PIE root *bhergh- (2) "high, elevated" (source also of Old Church Slavonic bregu "mountain, height;" Old Irish brigh "mountain;" Welsh bera "stack, pyramid;" Sanskrit b'rhant "high," brmhati "strengthens, elevates;" Avestan brzant- "high," Old Persian bard- "be high;" Greek Pergamos, name of the citadel of Troy). Obsolete except in place-names and southwest England dialect by 1400; revived by modern archaeology.
