restlessness
UK: ˈrɛstləsnəs | US: ˈrɛstləsnəs
n. the inability to stay still or relaxed, often due to anxiety or boredom
n. a state of constant agitation or unease
The word "restlessness" combines "rest" (from Old English ræst, meaning "quiet" or "repose") with the suffix "-less" (Old English -lēas, meaning "without"). The addition of "-ness" (Old English -nes, forming abstract nouns) transforms the adjective "restless" into a noun describing a state of being. The term evolved to describe both physical and emotional agitation, reflecting the human experience of being unable to find calm.
