cat

From Middle English cat, catte, from Old English catt (“male cat”), catte (“female cat”), from Proto-West Germanic *kattu, from Proto-Germanic *kattuz, generally thought to be from Late Latin cattus (“domestic cat”) (c. 350, Palladius), from Latin catta (c. 75 A.D., Martial), possibly from an Afroasiatic language. Doublet of gato.

A loan from Afroasiatic into Indo-European would roughly match how the animal itself spread, as genetic studies suggest domestic cats first began to spread out of the Near East / Fertile Crescent during the Neolithic, especially after they became popular and domesticated in Egypt 4000 years ago; they were found in Greece and Italy later, 2500 years ago. However, every proposed source word has presented problems. Adolphe Pictet and many subsequent sources refer to Barabra (Nubian) [script needed] (kaddîska) and "Nouba" (Nobiin) ⲕⲁⲇⲓ̄ⲥ (kadīs, “kadīs”) as possible sources or cognates, but M. Lionel Bender says the Nubian word is a loan from Arabic قِطَّة (qiṭṭa), which has long been thought to be non-Arabic in origin. Jean-Paul Savignac suggests the Latin word is from an Egyptian precursor of Coptic ϣⲁⲩ (šau, “tomcat”) suffixed with feminine -t, but John Huehnergard says "the source [...] was clearly not Egyptian itself, where no analogous form is attested."

It may be a wanderword. Kroonen says the word must have existed in Germanic from a very early date, as it shows morphological alternations, and suggests that it might have been borrowed from Uralic, compare Northern Sami gađfe (“female stoat”) and Hungarian hölgy (“stoat; lady, bride”) from Proto-Uralic *käďwä (“female (of a fur animal)”).
