What does acumen mean?
Acumen refers to the ability to think quickly, judge accurately, and make sound decisions, particularly within a specialized area of activity such as business, law, finance, or politics. The word carries a distinctly positive connotation: to have acumen is to possess a penetrating intelligence that cuts through complexity to what really matters. In modern usage it rarely stands alone; speakers typically pair it with a domain modifier, as in 'business acumen' or 'political acumen', signaling expertise that goes beyond book learning into shrewd, practical judgment. It is a formal term, common in journalism, biography, and professional writing, and it functions as an uncountable noun with no plural form. Derived from the Latin acumen, meaning a sharp point, the word preserves that image of pointedness metaphorically — a mind as sharp as a needle. Its close relatives include acute and acuity, all tracing back to the same Latin root acus, meaning needle. For anyone describing decisive, perceptive intelligence in action, acumen remains one of English's most precise and respected choices.

Acumen comes from the Latin word for a sharp point — the same root that gave us 'acute' — so calling someone's business acumen sharp is literally true.
