Etymology 1

Masculinized form from Middle French escroue, from Old French escroe, from Latin scrōfa, originally “sow (female pig)”;[1] 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)

1. nut (that fits on a bolt), female screw

Etymology 2

From Middle French escrou (“scrap, strip of parchment, scroll”), from Old French escroe, from Old Dutch *skrōda (“end, flap”) (compare Middle Dutch scrōde), from Proto-Germanic *skrudaz, derivative of Proto-Germanic *skrudaną (compare Dutch schrooien (“to shred”)). Cognate with English scrow, scroll.
