notch
The word evokes a physical image of a precise, angular indentation, often used for marking progress or creating a mechanical fit. When used to describe a cut, it suggests a deliberate and functional modification of a material's edge. In a figurative sense, it describes a discrete step in a hierarchy or a scale of quality. This usage implies that progress happens in measurable increments rather than a smooth gradient, as seen in the phrase "a notch higher."
