The word "smooth" originates from Old English smōth, meaning "even, polished, gentle." It evolved from Proto-Germanic smōthaz, linked to the idea of effortless motion or lack of friction. Over time, the spelling standardized to "smooth," absorbing the original root without distinct prefixes/suffixes. Its semantic core—physical evenness and metaphorical calmness—remains consistent.
