discomfit

Etymology

From Old French desconfit, past participle of desconfire (“to undo, to destroy”), from des- (“completely”), from Latin dis- + confire (“to make”), from Latin conficio (“to finish up, to destroy”), from com- (“with, together”) + facio (“to do, to make”). Later sense of “to embarrass, to disconcert” due to confusion with unrelated discomfort.
