英文词源

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].
=> 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.
