- barrow (n.1)
- "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 (cf. Old Saxon, Old Frisian, Old High German berg "mountain," Old North bjarg "rock"), from PIE root *bheregh- "high, elevated" (cf. Old Church Slavonic bregu "mountain, height," Old Irish brigh "mountain," Sanskrit b'rhant "high," Old Persian bard- "be high"). Obsolete except in place-names and southwest England dialect by 1400; revived by modern archaeology.
In place-names used of small continuously curving hills, smaller than a dun, with the summit typically occupied by a single farmstead or by a village church with the village beside the hill, and also of burial mounds. [Cambridge Dictionary of English Place-Names]
Meaning "mound erected over a grave" was a specific sense in late Old English. Barrow-wight first recorded 1869 in Eirikr Magnusson and William Morris's translation of the Icelandic saga of Grettir the Strong.
