Stilts are walking devices that make the person wearing them much taller than usual. When you use stilts, you stand on foot rests and walk along far above the ground.
Stilts are special poles, either for walking tall or for supporting a structure that might otherwise be damaged by water. You can sometimes see people walking on stilts at a circus or parade, and you can see houses on stilts in some beachfront communities. Walking stilts are sometimes also used by workers, including the stilts worn by window washers and fruit farmers.
