Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'Горчица' (Gorchitsa) which is correct for the condiment. The color 'горчичный' (gorchichnyy) is a direct equivalent. The plant is 'горчица'. No major trap, but the idiomatic uses ('cut the mustard') have no direct translation.
Common Mistakes
- Using 'a mustard' to refer to a single type (better: 'a type of mustard'). Confusing 'mustard' as a color modifier ('mustard shirt' not 'mustard-colored shirt' is acceptable).

FAQ
Frequently Asked Questions
It is primarily uncountable when referring to the condiment substance ('I added mustard'). It can be countable when referring to types ('three different mustards'). The plant is countable ('mustards grow in the field').
It is a chemical warfare agent, not related to the condiment. Its name comes on its yellow-brown color and sometimes a faint odor reminiscent of mustard, garlic, or horseradish.
It comes from Old French 'moustarde', from Latin 'mustum' ('must', meaning young wine), because the condiment was originally made by mixing crushed seeds with 'must' (grajuice).
In modern standard English, 'mustard' is not used as a verb. Archaically, it could mean to season with mustard, but this is obsolete.
