Handier → It is formed from "hand" (from Old English "hand", meaning the part of the body at the end of the arm used for grasping) and the suffix "-ier" (indicating a comparative form). The word "handier" means more convenient or easier to handle, as it relates to the ease of using one's hands.
Think of the word 'hand' which relates to how we use our hands to do things. When something is 'handier', it means it's easier to manage or use with your hands.
