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].
=> double, duplicity, fold, ply, two - duplicate (adj.)
- mid-15c., "having two parts, double," from Latin duplicatus, past participle of duplicare "to double," from duo "two" (see two) + plicare "to fold" see ply (v.1)). Meaning "exactly corresponding, that is an exact copy of" is from 1812.
- duplicate (v.)
- 1620s, "to double," from Latin duplicatus, past participle of duplicare (see duplicate (adj.)). Meaning "make an exact copy" is from 1640s (implied in duplicated). Related: Duplicating. The noun is first recorded 1530s.
