The word "speed" originates from Old English spēd, meaning "success, prosperity, swiftness." Over time, its meaning narrowed to focus primarily on swiftness or rapid motion. The root is Germanic, linked to Dutch spoed and German Spur (track), reflecting an early association with progress or forward movement. The modern sense of "velocity" emerged by the 14th century, influenced by the concept of success being tied to quick action.
