the.com/appendage

Anything your body grew that it didn't strictly need a second opinion on.

means Something attached to a larger or more important main part, like a limb, tail, or minor addition.

from From Latin 'appendere' meaning 'to hang upon' — the same root that gave us 'append' and 'pendant.' The 'pend' part is the key: it's related to things that hang or dangle, like a pendulum swinging from a fixed point. An appendage, etymologically, is just something hanging off the main business.
