Word Origin & History

measles
early 14c., pl. of M.E. masel, probably from M.Du. masel "blemish" (in pl. "measles"), from P.Gmc. *mas- "spot, blemish" (cf. O.H.G. masla "blood-blister"). There may have been an O.E. cognate, but if so it has not been recorded. Probably influenced by O.Fr. mesel "leprous," from L. misellus "wretched,
unfortunate," dim. of miser "wretched."
