Word Origin for emery
"granular mixture used as an abrasive," late 15c., from Middle French émeri, from Old French esmeril, from Italian smeriglo, from Vulgar Latin *smyrilium, from Greek smyris "abrasive powder" used for rubbing and polishing, probably a non-Greek word, perhaps from a Semitic source.
