flawless
UK: ˈflɔːləs | US: ˈflɔːləs
adj. without any imperfections or defects; perfect
adj. (of a performance, argument, etc.) completely accurate and excellent
The word "flawless" combines "flaw" (from Old Norse flaga, meaning "a slab of stone," later evolving to mean "a crack or defect") with the suffix "-less" (Old English -lēas, meaning "without"). Originally, "flaw" referred to physical cracks in objects, but by the 16th century, it broadened to abstract imperfections. Adding "-less" negates the flaw, creating a vivid image of absolute perfection—like a gemstone without a single blemish.
