Etymology

The word "idly" derives from the Old English "īdel," meaning "empty" or "useless," which evolved into "idle" in Middle English, retaining the sense of inactivity. The suffix "-ly" is a common adverbial marker in English, turning adjectives into adverbs. Thus, "idly" literally means "in an idle manner," reflecting actions done without energy or purpose.
