Our Hunspell-derived misspelling index lists 11 documented wrong-spelling variants for mustard, with forms such as "mmustard", "msutard", and "musatrd". Each variant represents a distinct typo pattern that appears often enough in corpora to be worth flagging, typically a doubled-consonant error, a silent-letter drop, or a vowel substitution.It also participates in 3 confusable-pair relationships, "muster", "mustang", "Mustafa", where similar look or sound leads writers to substitute one word for another in context.

Etymologically, the entry records: 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”)… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is mustard, spelled M-U-S-T-A-R-D, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.

Etymology

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.
