Definition of spoke

The word "spoke" in its modern usage refers to one of the component parts of a wheel that transmits power from the hub to the ground. The origin of the word spoke can be traced back to Old English, where it was spoc means "tongue" or "branch." This usage can be observed in the Middle English word spok, which still retained the original meaning of a branch or splinter. The association between the word spoke and wheel hubs can be traced back to the late Middle Ages around the 14th century. Spokes were added to wagon wheels to increase strength and durability, as the early wagon wheels were previously made of wooden slabs. These spokes were attached to the hub, and as the wheel rotated, they bent and straightened, allowing the wheel to turn smoothly. The use of the term spoke to describe these components was likely inspired by the shape of the spokes, which, when viewed from the side, could resemble the branches of a tree extending out from the hub, much like the tongue or branch of an Old English oak tree. From there, the term spread to other wheeled vehicles, such as carts, carriages, and eventually, bicycles and cars. Overall, the word spoke in its modern context is a strong testament to the historical evolution of wheel technology and the ancient language roots from which it has evolved.
