dwarf

From Middle English dwergh, dwerw, dwerf, from Old English dweorg, from Proto-West Germanic *dwerg, from Proto-Germanic *dwergaz.

Cognate with Scots droich, dwerch (“dwarf, midget”); Old High German twerc (German, Luxembourgish Zwerg (“dwarf”)); Old Norse dvergr (Danish dværg (“dwarf, midget”), Faroese dvørgur (“dwarf”), Icelandic dvergur (“dwarf”), Norwegian Bokmål dverg (“dwarf”), Norwegian Nynorsk dverg, verg (“dwarf”), Swedish dvärg (“dwarf”)); Old Frisian dwirg (Saterland Frisian Dwärch (“dwarf”), West Frisian dwerch (“dwarf”)); Middle Low German dwerch, dwarch, twerg (German Low German Dwarg (“dwarf”)); Middle Dutch dwerch, dworch (Dutch dwerg (“dwarf”)).

The Modern English noun has undergone complex phonetic changes. The form dwarf is the regular continuation of Old English dweorg, but the plural dweorgas would have given rise to dwarrows and the oblique stem dweorge- would have led to dwery. These forms are sometimes found as the nominative singular in Middle English texts and in English dialects. A parallel case is that of Old English burg giving burgh, borough, burrow, bury.
