The short, thick finger on your hand that helps you grab and hold things.
This word comes from an old word meaning 'thick' because the thumb is the thickest finger.
Your thumb is your hand's best helper! It's the strong finger that touches all your other fingers to help you pick up toys, hold your cup, and give thumbs up when something is awesome!
