What does rasp mean?
A rasp is both a rough file used to scrape and smooth materials and a grating sound produced by scraping, a dry throat, or a harsh voice. The related verb means to scrape a surface with this tool or to produce such a sound. The word commonly conveys friction, roughness, and intensity: a singer may have a rasping voice, a hinge may rasp as it moves, or a carpenter may rasp wood. In figurative use, “rasping” can describe nerves, sensations, or sounds that are abrasive and difficult to tolerate. The word is useful when precision matters because it distinguishes a coarse scraping quality from the smoother impression left by sanding or polishing. Its sound-based senses are especially evocative and appear frequently in descriptions of music, speech, breathing, and physical discomfort.
A coarse file used to scrape or smooth a hard surface; also, a rough grating sound.
"He used a metal rasp to remove the rust from the hinge."
The tool sense is countable and takes “a” or the plural “rasps.” The sound sense is usually countable when referring to a particular sound: “The door closed with a rasp.”
To scrape a surface with a rasp, or to make a harsh, grating sound.
"The metal gate rasped loudly when the wind pushed it open."
The verb is intransitive when describing a sound and transitive when a surface or object is being scraped: “She rasped the wood,” “The hinge rasped.”
The plural is standard for the tool and for individual instances of a grating sound.
"The workshop was filled with rasps, files, and other tools."
A rasp can mean both a tool that scrapes wood and the sound that roughens a singer's voice.

Etymology of rasp
The English noun and verb developed through Middle English from Old French raspe, a coarse file, associated with a Germanic root meaning “to scrape” or “rake.” The word was borrowed with the sense of a tool for working rough surfaces and later extended to the sound produced by scraping. Related forms include the tool-bearing “rasper,” the surgical rasp “raspatory,” and “raspberry,” which belongs to the same historical rasp word family.
