thumb

Hitchhiker's lifted digit

The thumb is the short, thick digit set apart from the four fingers of the human hand.

Its opposability—the ability to touch each fingertip—distinguishes primate hands and enables gripping.

To thumb is to turn pages with the thumb, or to hitchhike by signaling with an extended thumb.

A rule of thumb is a rough practical guideline.

To be under someone's thumb is to be controlled by them.

All thumbs describes clumsiness.
