What does the notation "cc" indicate on letters, memos, and emails?

The notation "cc" on letters, memos, and emails stands for "Carbon Copy." It is a method used to send a duplicate of a document or message to someone other than the primary recipient. The practice originates from the use of carbon paper, which allowed for the creation of copies without the need for a photocopier.

The inclusion of "cc" serves a crucial function in communication, allowing the sender to keep others informed about the contents of the correspondence while also indicating to all recipients who else received the same message. This enhances transparency and facilitates collaborative communication among team members or stakeholders.

In the context of professional writing, while "Courtesy Copy" is a phrase that might be surmised in casual contexts, it is not formally recognized as the meaning behind "cc." The other terms listed such as "Communication Channel" and "Collation Copy" are not related to the usage of "cc" in correspondence. Thus, understanding that "cc" denotes "Carbon Copy" reinforces an important aspect of professional communication etiquette.
