köken: Inherited from Middle French chat, from Old French chat, from Late Latin cattus.
aile: à bon chat, bon rat, à ne pas mettre un chat dehors, absent le chat, les souris dansent, acheter chat en poche, appeler un chat un chat, arbre à chat, avoir d'autres chats à fouetter, avoir un chat dans la gorge, c'est le chat qui se mord la queue, chat à neuf queues
köken: Inherited from Old East Slavic котъ (kotŭ), from Proto-Slavic *kotъ. Should be separated from коти́ться (kotítʹsja) (related to око́т (okót), catulus), the connection with this word is secondary.
köken: From the onomatopoeia бес-бес (bes-bes, “the sound used to call a cat”). Compare Tatar песи (pesi, “cat”). Any relation with Proto-Common Turkic *mušuq ~ *mišik, from earlier *pïšïk (“cat”) cannot be satisfactorily made.
köken: 괴 (goe, “cat”, now largely obsolete) + -앙이 (-ang'i, diminutive suffix). First recorded in 1690, and became popular in the late 19th century. Ultimately from Old Korean *kwò(y)ní, attested in the twelfth-century wordlist Jilin leishi; see 괴 (goe) for more.
