PIE*dheu, 煙塵，煙霧，詞源同dust, deaf, dumb.

dull

dull: [13] Dull originally meant ‘slow-witted’. It was borrowed from Middle Low German dul, a descendant of the prehistoric Germanic adjective *dulaz, which also produced German toll and Old English dol ‘stupid’ (the Old English adjective does not seem to have survived beyond the 10th century). The modern meaning ‘boring’ developed in the 15th century. The now littleused dullard [15] is a derivative (reflecting the adjective’s original sense), as also is probably dolt [16].

dull (adj.)

c. 1200, "stupid;" early 13c., "blunt, not sharp;" rare before mid-14c., apparently from Old English dol "dull-witted, foolish," or an unrecorded parallel word, or from Middle Low German dul "slow-witted," both from Proto-Germanic *dulaz (cognates: Old Frisian and Old Saxon dol "foolish," Old High German tol, German toll "mad, wild," Gothic dwals "foolish"), from PIE *dheu- (1) "dust, vapor, smoke" (and related notions of "defective perception or wits"). Of color from early 15c.; of pain or other sensations from 1725. Sense of "boring" first recorded 1580s.
