Etymology
The word 'copy' entered English in the 14th century from the Old French 'copie', which itself derived from the Medieval Latin 'copia', meaning "transcript" or "abundance." This Latin term originated from the classical Latin 'copia', signifying "plenty" or "abundance," a compound of 'co-' (a variant of 'com-', meaning "with") and 'ops' (meaning "power, wealth"). The semantic evolution from "abundance" to "transcript" is thought to have occurred in Medieval Latin, where the phrase 'copia describendi' ("an abundance for describing") came to mean the right to transcribe or the transcript itself. This meaning of a reproduction was then inherited by English, shifting from the concept of plentiful material to the act and result of duplicating it.
Analysis
The word 'copy' is a simplex loanword from Latin. It does not contain separable morphemes in its modern English spelling.
