Etymology
Origin of excitable
From the Late Latin word excitābilis, dating back to 1600–10. See excite, -able
Explanation
Someone who's excitable easily becomes excited, enthusiastic, or eager. A five-year-old will be especially excitable at her own birthday party. When you describe someone as excitable, you'll usually mean it as a mild criticism — the person is easily overstimulated, and becomes excited far too readily. Passing out candy in an elementary school classroom — or bacon among a bunch of puppies — will demonstrate just how excitable a group can be. Excitable comes from the Latin excitabilis, "inciting or animating," from excitare, "stir up" or "awaken."
