What does "cc" stand for in the context of messaging?

In the context of messaging, "cc" stands for "carbon copy." This term originated from the practice of using carbon paper to create duplicates of documents, allowing one to send the same message to multiple recipients at once. When someone is included in the "cc" field of an email, it signifies that they are receiving a copy of the message for their information but are not the primary audience. It is an important feature in professional communication, facilitating transparency and allowing all parties to stay informed without placing the same demands for response or action on the individuals being copied.

The other terms do not accurately represent the conventional meaning of "cc" in messaging, making this term unique and widely recognized in email communication.
