Why turkey has the same name as Turkey
early 15c., from Old French duplicite (13c.), from Late Latin duplicitatem (nominative duplicitas) "doubleness," in Medieval Latin "ambiguity," noun of quality from duplex (genitive duplicis) "twofold." The notion is of being "double" in one's conduct (cf. Greek diploos "treacherous, double-minded," literally "twofold, double").
