The term LEG EXTENDER can be summarized as a STILT, which is a five-letter word. A stilt is a device used to raise the height of a person or object. It consists of two long poles with footrests attached to them, allowing the user to stand at a greater height than normal. Stilts are commonly used by performers, such as clowns and mimes, to add an element of surprise and comedy to their acts. They are also used in construction work, allowing workers to reach higher places.
