Origin of the word sleepless

"Sleepless" is a combination of two Old English words: "slæp," meaning "sleep," and "lēas," meaning "without" or "lacking." The word first appeared in Old English literature around the 10th century, though it likely existed in spoken language earlier. Its formation follows the standard pattern of adding the "lēas" suffix to create negative adjectives, as seen in words like "worthless" and "childless." The meaning of "sleepless" has remained consistent over time, describing a state of being without sleep, often due to worry, excitement, or a medical condition.
