cat: [OE] The word cat seems to have appeared on the European scene, in the form of Latin catta or cattus, around 1000 AD (the previous Latin word was fēlēs, source of English feline). No one is completely sure where it came from (although given the domestic cat’s origins in Egypt, it is likely to have been an Egyptian word), but it soon spread north and west through Europe. The Latin word reached English via Germanic *kattuz, later backed up by Anglo-Norman cat, a variant of Old French chat. [cat etymology, cat origin, 英语词源]
