Difference in Context and Connotation
To 'copy' means to make or produce something that is similar to another. A copy aims to replicate the content, appearance, or functionality of the original and is typically used when talking about the act of reproduction as an immoral or negative act of imitating or trying to deceive. To 'duplicate', however, means to make an identical or exact reproduction of an original, typically with the intention of having multiple versions that resemble the original as closely as possible. It is commonly used in contexts where the intention is to create additional identical or similar versions of an object or document, often for organizational or distribution purposes. Here are some examples:
