An Etymological Dictionary of the German Language/Annotated/Urbar

by Friedrich Kluge

Urbar, neuter, ‘produce, landed property,’ from Middle High German urbor, urbar, feminine and neuter, ‘copyhold, rent, income’; literally perhaps ‘tax, produce, rent’ (compare Gothic gabaúr, ‘tax’). Hence urbar, adjective, ‘arable,’ literally ‘bearing interest, productive’ (Modern High German only). —
