/ˌanfraktʃʊˈɒsᵻti/, U.S.

/ænˌfræktʃʊˈɑsədi/

Forms: 1600s amfractuosity, 1600s– anfractuosity.

Origin: A borrowing from French. Etymon: French anfractuosité.

Etymology: < French anfractuosité each of the sinuous depressions separating the convolutions of the brain, (chiefly in plural) winding cavity or depression in the ear, the surface of a bone, etc. (both 1503 in Middle French), (in anatomy) sinuousness (of a duct, passage, etc.) (1555) < post-classical Latin anfractuosus anfractuous adj. + Middle French -ité -ity suffix. Compare earlier anfractuous adj.Compare Spanish anfractuosidad (1555), Italian anfrattuosità (a1758). With the form in am- compare the forms and note at anfractuous adj.

a. A winding or sinuous route or passage (chiefly in plural); a turn, a bend; a fissure, a crevice. Also occasionally as a mass noun: the quality of being winding or sinuous.
