A carbon copy is made by using carbon paper. Carbon paper is a very thin sheet of paper coated on one side with a film of carbon in suspension. The carbon paper is placed between two sheets of paper when intending to write or type (with a typewriter) on one of the sheets and to produce a duplicate of the writing on the second sheet of paper. It is important to have the carbon side of the carbon paper resting on the paper that will be the duplicate. The term "carbon copy" (abbreviated cc) is used to indicate the duplicate. Now, when it is possible to create duplicate copies by other means, the term "carbon copy" continues to be used to refer to the duplicate copies.
In the context of letter writing, "cc" stands for "carbon copy." In the past, carbon paper was used to make copies of a document by placing it between two sheets of paper and writing or typing on the top sheet. When a person is listed as a "cc" on a letter, it means they will receive a copy of the letter for informational purposes, but they are not the primary recipient. This practice is still used in modern email correspondence to indicate additional recipients who are not the main addressee.

carbon copy Before copy machines were common, if you wanted several copies of a letter or memo, you would put several sheets of paper into the typewriter with carbon paper between the sheets. Then, after typing the item once, you had the original plus several carbon copies. Today, it is used to indicate a person or people to whom a memo or e-mail is being sent but to whom it is not addressed.
