Synonym Chooser
Some common synonyms of duplicate are copy, facsimile, replica, and reproduction. While all these words mean "a thing made to closely resemble another," duplicate implies a double or counterpart exactly corresponding to another thing.
a duplicate of a house key
The meanings of copy and duplicate largely overlap; however, copy applies especially to one of a number of things reproduced mechanically.
printed 1000 copies of the lithograph
Although the words facsimile and duplicate have much in common, facsimile suggests a close reproduction often of graphic matter that may differ in scale.
a facsimile of a rare book
While the synonyms replica and duplicate are close in meaning, replica implies the exact reproduction of a particular item in all details, but not always in the same scale.
a replica of the Mayflower
miniature replicas of classic cars
While in some cases nearly identical to duplicate, reproduction implies an exact or close imitation of an existing thing.
reproductions from the museum's furniture collection
