Usage
Where does the word cat come from? While cats may be more enigmatic and reclusive than dogs in real life, when it comes to the source of the word cat, it’s a bit easier to grasp. The origin of the word dog is one of the great mysteries of English etymology. Learn why in our slideshow “‘Dog,’ ‘Boy,’ And Other Words That We Don’t Know Where They Came From."The word cat is recorded in Old English, and hasn't changed much since. (Hey, if it isn’t broken why fix it?) The masculine form was catt, the feminine catte. The word cat is most likely related to the Late Latin cattus, source of some other cat words you may have heard, including the Spanish gato and French chat. Now that you know how cats got their name, why not find out how some of our other most beloved pets got theirs in the slideshow: "Where Do The Words For Our Pets Come From?"

Etymology
Origin of cat
First recorded before 900; Middle English cat, catte, Old English catt (masculine), catte (feminine); cognate with Old Frisian, Middle Dutch katte, Old High German kazza, Old Norse kǫttr; akin to Late Latin cattus, catta (first recorded in the 4th century, presumably with the introduction of domestic cats); further origin uncertain
Explanation
What's another name for the four-legged feline that lies around on your keyboard all day and purrs? You might call it “Fluffy,” but it’s also known as a cat. If you’re in the market for a pet cat, just make sure it meows, and doesn’t roar like the lion, tiger, or jaguar, all of which are in the same family as the housecat. Domesticated as long ago as ancient Egyptian times, the cat is a fixture not only in many homes, but also in a host of English expressions — like, “when the cat’s away, the mice will play,” “it’s raining cats and dogs,” and “the cat’s pajamas.”
