Handheld → It is formed from "hand" (from Old English "hand", meaning the part of the body at the end of the arm) and "held" (the past participle of "hold", from Old English "holdan", meaning to grasp or carry). The word "handheld" describes something that is designed to be held in the hand.
Think of something that is meant to be 'grasped' or 'carried' by your 'hand' — that's why handheld refers to devices you can hold easily.
