An appendage is something attached to a larger or more important body, like an arm, leg, tail, or even a smaller organization connected to a bigger one.
From Latin "appendere" meaning "to hang upon," with "ad-" (to) and "pendere" (to hang). The word pictures something literally hanging off the main part.
Calling something an “appendage” often hints that it’s secondary or less important, even if it’s physically attached. The same idea is used in biology, politics, and business to mark what’s central and what’s just hanging on.
