To cogitate is a fancy way of saying to think hard about. If you spend a lot of time figuring out exactly how your French teacher does her hair, you are cogitating in order to avoid conjugating.

Cogitate can be used both transitively or intransitively, which means you can cogitate on something, like your history project or why your computer never seems to work the way you want it to. Or you can simply sit in your room and cogitate.
