A small, portable computer that can be held in one hand.
He used his palmtop to take notes during the meeting.
Palmtop → It is formed from "palm" (from Old English *palm*, meaning the inner surface of the hand) and "top" (from Old English *top*, meaning the highest point or upper part). The word "palmtop" refers to a small computer or device that fits in the palm of the hand, emphasizing its compact size.
Think of the 'palm' of your hand, which is where you can hold something small, and 'top' meaning the upper part — a palmtop is a device that fits right in your palm.
