Etymology

Origin of appendage

First recorded in 1640–50; append + -age

Explanation

Use the noun appendage to describe something that’s attached to something larger. Your arm is an appendage to your body. Appendage often describes body parts, either on humans or animals. If it’s something that sticks out — like a finger, tail, or leg — chances are it can be called an appendage. The word can also be used figuratively to refer to something that’s associated with something larger or more important, like a husband who’s a mere appendage to his famous wife. In this sense, the word takes on a negative connotation: the appendage is not important.
