duplicates
Identical second versions
Duplicates are copies or exact matches of something else.
The word works as both noun and verb: you might find duplicates in a photo library, or duplicate a key at the hardware store.
To remove duplicates is to eliminate redundant items from a set.
A duplicate can also be a person who closely resembles another: She's a duplicate of her mother.
