A wheel is a round object that turns on an axle and helps vehicles and machines move or rotate smoothly.
“Wheel” comes from Old English “hwēol,” from Proto-Germanic “hweulaz.” It traces back to Proto-Indo-European “*kʷekʷlo-,” also the source of Greek “kyklos” (circle, cycle).
The wheel was such a powerful invention that its ancient root also gave us words like “cycle” and “bicycle.” Every car, clock, and hard drive hides wheels or wheel-like parts quietly spinning in the background.
