Thumb

The short, thick first digit of the human hand, located at the radial side. It is opposable in humans, enabling grasping and fine manipulation. Metaphorically, it can represent approval or hitchhiking. Its presence and function are crucial for tool use, communication, and a wide array of daily tasks. Its bone structure allows for significant dexterity and range of motion compared to the other fingers. Figuratively, to "thumb" something often means to handle or examine it roughly.
