How would you describe a person who shows extreme restlessness?

Describing a person who exhibits extreme restlessness is aptly captured by the term "fidget." This term indicates a tendency to move about nervously or restlessly, often involving small movements or actions that stem from anxiety or excitement. A person characterized as a fidget typically finds it hard to stay still, whether due to nervous energy, impatience, or general discomfort in their current state.

In contrast, other terms presented, such as figurehead, finicky, and fervent, do not convey the same sense of movement or restlessness. A figurehead typically refers to someone who holds a nominal leadership position but lacks real power or influence. Finicky describes an overly particular or picky attitude, which does not necessarily imply restlessness. Fervent suggests intense or passionate feelings, which may or may not correlate with a restless demeanor. Thus, describing a person as a fidget directly aligns with the notion of extreme restlessness.
