Etymology: "Slideway" is about as transparent as compounds get: it simply joins "slide" and "way," with "way" in its old sense of a track or path that something travels along. The "slide" half comes from Old English "slidan," meaning to glide or slip smoothly, and "way" goes back to Old English "weg," a route or road. Put together, the word describes a path built for things to glide along. In engineering use, the term names the rails, grooves, or strips on a machine tool, such as a lathe, along which a carriage or table travels. The compound thus takes a general idea of a smooth track and narrows it to a precise mechanical part, a pattern common in technical vocabulary where two plain English words combine into a specialist label.
