grating
UK: ˈɡreɪtɪŋ | US: ˈɡreɪtɪŋ
n. a framework of parallel or crossed bars, typically preventing access or admitting light or air
adj. harsh or irritating in sound or manner
The word "grating" derives from the verb "grate," which originally meant "to scrape" (from Latin gratus, past participle of radere "to scrape"). Over time, "grate" evolved to also refer to a framework of bars (likely due to the crisscrossing resemblance of scraped marks). The suffix "-ing" transforms it into a noun denoting the object (the barred structure) or an adjective describing a harsh, scraping-like quality (e.g., a grating noise).
