implex (adj.)

"intricate, complicated," 1710, from Latin implexus "interwoven, entwined," past participle of implectere, from assimilated form of in- "in" (from PIE root *en "in") + plectere "to plait, twine, braid" (from suffixed form of PIE root *plek- "to plait"). Used by 18c. critics in reference to plots.
