Word Origin & History
ravel
1582, "to untangle, unwind," also "to become tangled or confused" (1585), from Du. ravelen "to tangle, fray, unweave," from rafel "frayed thread." The seemingly contradictory senses of this word (ravel and unravel are both synonyms and antonyms) are reconciled by its roots in weaving and sewing: as threads become unwoven, they get tangled.
[ruh-vel; Fr. ra-vel]
