borough (n.)

Old English burg, burh “a dwelling or dwellings within a fortified enclosure,” from Proto-Germanic *burgs “hill fort, fortress” (source also of Old Frisian burich “castle, city,” Old Norse borg “wall, castle,” Old High German burg, buruc “fortified place, citadel,” German Burg “castle,” Gothic baurgs “city”), which Watkins derives from from PIE root *bhergh- (2) “high,” with derivatives referring to hills, hill forts, and fortified elevations.
