razor

The word "razor" traces a clear path from a physical action to the tool that performs it. Its core originates in the Latin verb rādere, meaning "to scrape, scratch, or shave," which itself may derive from the Proto-Indo-European root rēd-, also conveying the idea of scraping or gnawing. This verb passed into Old French as raser, and the agent suffix -or (from Latin -ātor) was attached to form a noun for the shaving instrument. Thus, the literal "scraper" or "shaver" evolved into the modern specialized term for a sharp blade designed specifically for removing hair.

Structure: raz(e) (to scrape) + or (agent/instrument) - raz(e): From Middle English rasen (to scrape, graze), from Old French raser (to scrape, shave), from Latin rāsus, past participle of rādere (to scrape, shave). Functions as the verbal root meaning "to scrape or shave." - or: A suffix of Latin origin (via Old French -eor, -our), used to form agent nouns indicating a person or thing that performs an action. In this word, it denotes an instrument.
