Ever wondered by copywriters call themselves copywriters and not say, writers or journalists or something that is not confusing?
Well, the origins of the word 'copy will help answer the conundrum
Lexicom.com says of the word 'copy': " Middle English (denoting a transcript or copy of a document): from Old French copie (noun), copier (verb), from Latin copia ‘abundance’ (in medieval Latin ‘transcript’, from such phrases as copiam describendi facere ‘give permission to transcribe’). "
Etymonline.com provides further insight of its origins
mid-14c., "written account or record," from Old French copie (13c.) and directly from Medieval Latin copia "reproduction, transcript," from Latin copia "an abundance, ample supply, profusion, plenty," from assimilated form of com "with" (see com-) + ops (genitive opis) "power, wealth, resources," from PIE root *op- "to work, produce in abundance."
Sense extended 15c. to any specimen of writing, especially MS given to a printer to be reproduced in type (Caxton, late 15c.). Meaning "a duplication, imitation, or reproduction" written or otherwise is from late 14c. Meaning "one of a set of reproductions containing the same matter" is from 1530s.
So there you have it, copywriting and copywriter use copy in its original meaning and not its modern meaning. That is however confusing.
What is also confusing and open to misinterpretation, are the many uses of the word, as a noun and as a verb. Lexico sets them out:
