Etymology
Origin of drowsy
Explanation
Drowsy means sleepy and having low energy. When you’re sitting in the warm sunlight after a big lunch, and you’re so drowsy you can’t keep your eyes open, it’s not the right time to try organizing your desk. Ah drowsy, a word that describes slow-moving lions and charming little towns equally well. It has a pleasant association to it, a nice cozy sleepiness, like the sort of feeling you have when you can’t exactly figure out why your eyes keep closing, they just do. Wine makes some people drowsy and a boring documentary will definitely do it to you. Drowsy comes from an Old English word meaning "falling," and has evolved into falling asleep.
