Word History

Etymology

Noun

Middle English metal, metall, borrowed from Anglo-French & Latin; Anglo-French metal, borrowed from Latin metallum "mine, quarry, substance obtained by mining, metal, mineral," borrowed from Greek métallon "mine, gallery of a mine, tunnel (in siege works)," from about the 1st century A.D. on also "metal, mineral," of uncertain origin

Note: A basic issue is the possible relation between the Greek noun and the verb metalláō "ask, inquire, question," attested since Homer. Métallon has been taken as a back-formation from this word, though etymologically the verb leads no further than the noun. (The explanation as from met' alla "[to look] for other things" is hardly convincing.) Perhaps more plausibly metalláō, along with métallon, has been taken as a technical term of miners, with a figurative sense taken up by epic poets and the original technical sense lost. R. Beekes (Etymological Dictionary of Greek) suggests a pre-Greek substratal origin, though -all- as a suffix—if that is the issue here—has a very restricted occurrence. The sense "metal," the only meaning carried into modern European languages, may be a back-formation from metalleúō "dig a mine or tunnel, get by mining."
