adjectiveB1IELTSTOEFLSAT

Unable to rest, relax, or be still; uneasy, constantly moving, or characterized by a lack of quiet.

Restless can describe physical movement (tossing and turning in bed) or a mental state of anxiety, boredom, or impatience.

The story behind the word. Dating back to Old English 'restlēas', the word combines 'rest' (meaning quiet, sleep, or freedom from toil) with the suffix '-leas' (modern '-less', meaning without). It has remained virtually unchanged in meaning for over a thousand years.
