The word "rasp" is spelled with four letters, but it contains five sounds when pronounced. It starts with the voiced alveolar fricative /r/, followed by the unvoiced alveolar fricative /æ/. The third sound is /s/, which is also unvoiced and alveolar. The fourth sound is the voiced bilabial plosive /p/. Finally, the word ends with the unvoiced bilabial fricative /f/. Despite having only four letters, "rasp" is a complex word when it comes to phonetic transcription.
Rasp, as a verb, is defined as the action of grinding or scraping something with a rough or abrasive surface in order to make it smooth or to remove small pieces. This can be done using a rasp tool, which is a file-like instrument made of a rough surface with small, pointed, and raised teeth. The act of rasping typically produces a coarse and scraping sound.
As a noun, rasp refers to both the tool itself and the sound produced by using it. In terms of the tool, a rasp is a handheld instrument used primarily by carpenters, sculptors, or woodworkers to shape or smooth wood, metal, or other materials. The rough surface of the rasp utilizes its teeth to remove small amounts of material with each stroke. The sound generated by using a rasp is characterized by a grating, scratching, or scraping noise, resulting from the contact between the tool and the surface being worked on.
In a figurative sense, rasp can also be used to describe a sharp or harsh tone of voice or manner of speaking. When someone speaks or communicates in a rasp, it implies that their voice is rough, harsh, or strained, often indicating irritation, anger, or discomfort.
• A kind of rough file; a fruit, so called from its roughness.
• To rub or grate with a rough file or rasp.

The word "rasp" has Middle English roots and can be traced back to the Old French word "raspe" or "râpe", which also meant "rasp". This Old French term comes from the Latin word "raspa" or "raspatorium", meaning "a scraper or scraper-like instrument". Ultimately, this Latin word is derived from the verb "radere", meaning "to scrape or shave". The term "rasp" has been used since at least the 14th century to refer to a coarse file or woodworking tool with roughened surfaces used for shaping or smoothing materials like wood or metal.
