Meaning

noun a lightweight triangular scarf worn by a woman

originBorrowed from French fichu (“(noun) triangular scarf; (adjective) got up, put together”) (in the sense of something thrown on without much thought), from ficher (“to drive something (such as a nail) by its point”), ultimately from Latin fīgō (“to fasten, fix; to pierce, transfix; to drive (a nail)”), from Proto-Indo-European *dʰeygʷ- (“to set up”).
