mostaza
/mosˈtaθa/ · B2 · noun · f
mustard
🌭 mostaza = mosto (must, grape juice) + -aza; mustard was mixed with must
Spanish mostaza and English mustard share a root: the Romans ground mustard seeds and mixed them with mosto (unfermented grape juice, 'must') to make a paste. So mostaza = the must-paste condiment. Say mos-TA-tha, stress on TA.
