The full form of cc is Carbon Copy. The abbreviation CC stands for carbon copy. This phrase originated from the process of carbon copying, which involves sandwiching a carbon paper between two pages and writing on the top sheet. When you press the tip of your pen against the top page to write something, it leaves a duplicate mark on the second sheet. Place extra carbon papers and paper sheets between the top and bottom papers to make more carbon copies.
