Morphology

sleepless = sleep (semi-transparent) = sleep + less

The literary sense 'always watchful' is figuratively derived from 'without sleep' and may not be obvious as a literal inability to sleep to learners.

Etymology

The word sleepless can also be used in a poetic or old-fashioned way to mean 'always watchful' because someone who is 'without sleep' is awake and alert. That's why writers use sleepless for guards, parents, or keepers who stay awake to watch over others.
