I believe the answer is:

edition

I'm a little stuck... Click here to teach me more about this clue!

'copy' is the definition.
(I have seen 'copy of work' mean 'edition' so perhaps 'copy' could also mean 'edition')

Can you help me to learn more?

(Other definitions for edition that I've seen before include "Volume" , "Something impressed" , "single programme" , "Total number of copies issued (of book)" , "Particular version of a published text" .)
