appendage
UK: əˈpɛndɪdʒ | US: əˈpɛndɪdʒ
n. a subordinate or auxiliary part attached to a main structure (e.g., a limb or tail)
n. (figurative) an adjunct or secondary feature
Derived from Latin appendere ("to hang upon"), via Old French apendre. The root append retains its original sense of attachment, while -age (from Latin -aticum) denotes a resultant state or collective noun. The word evolved in Middle English to describe both physical attachments (e.g., limbs) and abstract additions.
