History
From Middle English dull, dul (also dyll, dill, dwal), from Old English dol (“dull, foolish, erring, heretical; foolish, silly; presumptuous”), from Proto-West Germanic *dol, from Proto-Germanic *dulaz, from earlier *dwulaz, a variant of *dwalaz (“stunned, mad, foolish, misled”), from Proto-Indo-European *dhwel-, *dhewel- (“to dim, dull, cloud, make obscure, swirl, whirl”). Cognate with Scots dull, doll (“slow to understand or hear, deaf, dull”), North Frisian dol (“rash, unthinking, giddy, flippant”), Dutch dol (“crazy, mad, insane”), Low German dul, dol (“mad, silly, stupid, fatuous”), German toll (“crazy, mad, wild, fantastic”), Danish dval (“foolish, absurd”), Icelandic dulur (“secretive, silent”), West-Flemish dul (angry, furious).
* As a German surname, from dialectal tull (“stout, corpulent”) (see the adjective doll), or a variant of Thiel. See Duell. * As a Scottish surname, it is a habitational name from Dull in Perthshire (see Etymology 2). * As an English surname, variant of Dill, Doel.
Possibly from Pictish [Term?], cognate with Proto-Brythonic *dol (“meadow”).
Probably from Irish dul, dol (“loop, noose, snare”).
