duplicate: duplicate: [15] Like its close relative double, duplicate comes ultimately from Latin duplus ‘two-fold’, a compound adjective based on Latin duo ‘two’ and an Indo-European element *plwhich denoted ‘folding’ (it is present also in English fold and ply). English acquired this in the 16th century, and its synonym duplex (based on the extended stem *plic-) in the 19th century. In Latin, duplus formed the basis of a verb duplicāre ‘make twofold, double’, from whose past participle English gets duplicate, while duplex has given us duplicity [15].
