canine (English)
Where does "canine" come from?
The English adjective canine derives from the Latin 'canīnus', meaning 'of dogs, dog-like', which is formed from 'canis' meaning 'dog' combined with the suffix '-īnus'[1][3]. The Latin noun 'canis' traces ultimately back to the Proto-Indo-European '*ḱwṓ' or '*ḱun-', meaning 'dog'[2]. Along the way, the term also entered French as 'canin' before taking its modern English form.
