drundi, pres. dryn, to roar. This root word is common to Goth., Scandin., Fris., and Dutch; for Ulf. drunjus = φθόγγος, Róm. x. 18, is a sufficient proof; in Swed. we have dröna, and drön neut.; Dan. dröne and drön; Dutch dreunen; North. E. to drone, as a cow; Fris. dröne; the mod. High Germ. dröhnen was, in the 17th century, borrowed from Low Germ. In old Icel. no instance happens to be on record, except dryn-rann in Gsp. 23, Fas. i. 480; in mod. usage it is freq. enough, and the absence in old writers seems to be accidental; draugr dimmr og magr, drundi í björgum undir, Snót 226, a ditty by Stefan Olafsson; drynja and dynja are different in sense, drynja denotes roaring, dynja crushing; þá heyrði hilmir hátt við kletta drafnar drynja dunur þungar, of the roaring surf, Od. (poët.) v. 401.
