From Middle English mustard, from Old French moustarde (French moutarde), from moust (“must”), from Latin mustum. Compare Saterland Frisian Muster (“mustard”), Dutch mosterd (“mustard”), German Low German Musterd (“mustard”), Icelandic mustarður (“mustard”). Displaced Middle English senep, from Old English senep, from Latin sināpi (“mustard”). Sometimes mistakenly thought to come from Latin mustum ardens, but such a Latin phrase is not attested, and it is well understood that that the final -ard is derived from Old French -arde. Doublet of mostarda.
