caudal (English)
Where does "caudal" come from?
The word 'caudal' traces its roots back to the Proto-Italic *kaudā, meaning 'tail,' which likely originated from a Proto-Indo-European term related to things that are cleaved or separated. By the time it reached Latin as 'caudālis,' it combined this root with a suffix to describe things possessing a tail. Today, English retains this usage to describe parts of the body located toward the hind or tail end.
