The word 'whippletree' originates from Old English 'hwippl' (meaning to turn or twist) and 'treow' (meaning tree). A whippletree is a device that helps to turn or twist the force from a draft animal to the implement it is pulling, hence the name.
Think of 'turning' ('hwippl') and 'tree' ('treow') to remember that a whippletree is a tool that helps to turn the force of a draft animal.
