adj. of the highest quality; excellent
adj. first-rate; outstanding
The word "top-notch" originated in the early 19th century, combining "top" (meaning the highest point) and "notch" (referring to a cut or mark used to indicate quality or rank). In literal terms, the highest notch on a measuring stick or tally represented the best possible standard. Over time, the phrase evolved into an adjective describing anything of superior quality, retaining its vivid imagery of being "at the top of the scale."
