To describe a language that is copied, you can use the word "duppcate" or "reppcate". For example, you could say "This language is a duppcate of the original language" or "This language is a reppcate of the original language."
Alternatively, you could use the word "derivative" to describe a language that has been developed or derived from an existing language. For example, you could say "This language is a derivative of the original language, with some modifications and additions."
It's also possible to use the phrase "based on" to describe a language that has been influenced by or developed from an existing language. For example, you could say "This language is based on the original language, with some changes and additions."
