caudal (English)
Where does "caudal" come from?
The English adjective 'caudal', meaning pertaining to a tail or hind part, was borrowed from the Latin word 'caudālis', which translates to 'having a tail'[1]. This Latin term builds upon 'cauda', meaning 'tail', combined with the suffix '-ālis'[2]. Going further back, 'cauda' stems from the Proto-Italic '*kaudā'[3][4]. This ultimately traces back to the Proto-Indo-European root '*keh₂u-d-eh₂', meaning 'cleaved, separate', which itself derives from '*keh₂w-'[3][4].

- The descent from Proto-Italic '*kaudā' to Proto-Indo-European '*keh₂u-d-eh₂' is considered a possible rather than certain historical connection. [3] [4]
