Here's a breakdown of its linguistic journey:
* Old French: "rasoir"
* Middle English: "rasour"
* Modern English: "razor"
The Old French word itself was likely borrowed from Vulgar Latin "*rasiorium*", which was a diminutive form of "*radius*", meaning "ray" or "spoke".
The connection to a razor lies in the idea that a razor's blade, like the spoke of a wheel, is a thin, sharp, and radiating point.
