écrou

== French == === Pronunciation === IPA(key): /e.kʁu/ === Etymology 1 === Masculinized form from Middle French escroue, from Old French escroe, from Latin scrōfa, originally “sow (female pig)”; compare Occitan escrofa (“screw nut”), Sicilian scrufina (“screw nut”). The change in meaning is also found in Spanish puerca, Portuguese porca, both “sow; screw nut”, and is based on the fact that a boar's penis has a screw-like tip, making the sow's vulva equivalent to a screw nut by analogy. ==== Noun ==== écrou m (plural écrous) nut (that fits on a bolt), female screw === Etymology 2 === From Middle French escroue (“register, file; piece, strip”) from Old French escroe, from Frankish *skrōda (“piece”). Compare English escrow, scroll. ==== Noun ==== écrou m (plural écrous) prison register, prison admission form ===== Derived terms ===== écrouer levée d'écrou === References === === Further reading === “écrou”, in Trésor de la langue française informatisé [Digitized Treasury of the French Language], 2012 === Anagrams === coeur, cœur coure
