Forms
canis m or f (genitive canis); third declension[1] The older nominative canēs is found once each in Ennius, Plautus, Lucilius and Varro.[2][3] The ablative is always cane and the genitive plural canum.[2][4]
Etymology
It is inherited from Proto-Italic *kō, inherited from Proto-Indo-European *ḱwṓ (“dog”) (accusative ⟨*ḱwon-m̥⟩, genitive ⟨*ḱun-os⟩).[2][1] The ablative ⟨cane⟩ and genitive plural ⟨canum⟩ show an old consonant stem, so the nominative was first ⟨canēs⟩; de Vaan explains the vowel /a/ by a change of ⟨*wo⟩ to ⟨*wa⟩ in the accusative ⟨*kwanem⟩, on which a new paradigm was built.[2] The TLL also notes the unexpected vowel.[5]
Cognate with Old Irish cú (“dog”), Welsh ci, Sanskrit श्वन् (śván-), Ancient Greek κύων (kúōn), Armenian շուն (šun), Lithuanian šuõ, Gothic 𐌷𐌿𐌽𐌳𐍃 (hunds) and Old English hund, all “dog”.[2][3] Ancient scholars linked it with canō (“to sing”).[5]
Earliest recorded meaning
Köbler dates it from Livius Andronicus;[6] de Vaan from Plautus.[2] Ennius has sī mē canis memorderit, “if a dog has bitten me”.[3]
Semantic evolution
Canis is “a dog, hound”, male or female.[3][4][1] Applied to people it is a term of abuse for a snarling or shameless person, and also for a watchdog or a hanger-on.[3][1] It names the Dog Star, Sirius, or the constellation Canis Major (Cicero's Aratea: fervidus ille canis, “that burning dog”), the lowest throw at dice (Propertius), and with marīnus a dogfish or shark.[3][1] In Plautus it seems to be a restraint for criminals, carried with the furca.[3]
Church Latin glosses it “dog”.[7] Köbler records it widely in the early medieval laws.[6]
