Selected source glosses provide context, not a complete modern definition inventory

From Middle English drosse, dros, from Old English drōs, from Proto-Germanic *drōhs (“dregs, sediment”). Also compare Old English drōsna, drōsne (“a ground, sediment, lees, dregs, dirt, ear wax”), from Proto-Germanic *drōhsnǭ, *drōhsnō (“dregs, sediment”), derived from *drōhs. Alternatively, this may be from *dragjō + *-snō (“yeast, sediment”; compare *dragjō (“yeast”)), as if from *drēcg + -sn. Ultimately from Proto-Indo-European *dʰrā́ks (“sediment, yeast”). Cognate with Scots dros, drose, drosse (“small particles, fragments, dross”), Middle Dutch droes (“dregs”), Dutch droesem (“dregs”), German Drusen (“lees, dregs”), Latin fracēs (“grounds or dregs of oil”). Related also to drast, dregs.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
