anfractuous (adj.) Look up anfractuous at Dictionary.com
1620s, "full of windings and turnings," from Latin anfractuosus "roundabout, winding," from anfractus "a winding, turning, a bending round," especially "a circuitous route," also figuratively, in rhetoric, "circumlocution," from am(bi)- "around" (see ambi-) + fractus, past participle of frangere "to break" (see fraction). T.S. Eliot uses it in the French sense "craggy," which probably he got from Laforgue. Related: Anfractuosity (1590s).
