Etymology: "Drossiest" is an inflected form: the superlative of "drossy," meaning most drossy, the most full of worthless residue. So the real story belongs to "dross," the word it is built on. "Dross" comes from Old English "drōs," which referred to the scum or sediment that rises to the surface or settles out when metal is smelted and purified. Smiths and refiners skimmed it off as the unusable part left behind once the valuable metal had been extracted. The word's roots reach back to Proto-Germanic, and the same metallurgical sense carried over into Middle English, where it kept its focus on impurities that rose from molten metal. Over time "dross" widened from the literal slag of the forge to any worthless leftover, and "drossy" followed the same path, describing things as full of dross. The suffix "-y" simply turns the noun into an adjective meaning "characterised by," and the superlative "drossiest" marks the highest degree of that quality.
