Feeling tired and without energy, often leading to a lack of interest in activities or tasks.

Listless → It is formed from "list" (from Old English *list*, meaning desire or inclination) and "-less" (meaning without). The word "listless" describes a state of being without desire or inclination, often resulting in a lack of energy or enthusiasm.
Think of being 'without' ('-less') any 'desire' ('list') — that's why listless means lacking energy or enthusiasm.
