Acumen

Part of speech: noun

Pronunciation: /ˈækjʊmən/

Definitions

1. Keen insight and good judgment in understanding and dealing with things, especially in business or practical matters

3. A sharp discernment or astuteness that enables one to effectively navigate challenges and opportunities in various contexts

Etymology: Before it meant keen judgment, "acumen" was a plain physical thing: the sharp point of a weapon or a pointed tip of any kind. The Latin "acūmen" came from "acuere," to sharpen, and that same root gave English "acute" and "acupuncture." The image of a needle-sharp point is still buried in the word, and the mental sense grew out of it by metaphor, the way we speak of a sharp mind or a keen edge. The word is a noun, borrowed directly from Latin, so English took the whole word rather than picking it up through French. Its shift from a literal point to a quality of the intellect is the centrepiece: the same figure of sharpness that describes a blade describes a quick, penetrating understanding.
