Other forms: discomfitures
Discomfiture is a state of being embarrassed and a little confused. There is nothing quite like the discomfiture of being abruptly reprimanded by your favorite teacher.
Discomfiture comes from discomfit, which originally meant "defeat in battle," from the Latin fortis, "strong." The meaning of discomfiture evolved over time from "state of having been defeated or thwarted" to "perplexed embarrassment." Being ignored by your friends would definitely cause discomfiture, and so would confidently talking in French class about your dream of being a hair stylist, only to realize you've been saying "horse stylist" the whole time.
