Most people are awake during the day and asleep at night, but if you work the night shift or suffer from insomnia, you might also be awake at night. When awake is used as a verb, it means "wake up:" "I watched my kitten awake from a deep sleep and yawn." Awake comes from two Old English roots, āwæcnan, "to arise," and āwacian, "to revive."
