Origin
Early 17th century; earliest use found in Philemon Holland (1552–1637), translator. From classical Latin emplecton, type of masonry (Pliny) from Hellenistic Greek ἔμπλεκτον, type of masonry (attested as a Greek word in the classical Latin author Vitruvius), use as noun of ἔμπλεκτος inwoven from ἐμ-, variant (before a labial) of ἐν- + πλεκτός plaited, twisted, after ἐμπλέκειν to plait or weave, entwine.
