English Synonyms and Antonyms
Sharpness, acuteness, and insight, however keen, and penetration, however deep, fall short of the meaning of acumen, which implies also ability to use these qualities to advantage. There are persons of keen insight and great penetration to whom these powers are practically useless. Acumen is sharpness to some purpose, and belongs to a mind that is comprehensive as well as keen. Cleverness is a practical aptitude for study or learning. Insight and discernment are applied oftenest to the judgment of character; penetration and perspicacity to other subjects of knowledge. Sagacity is an uncultured skill in using quick perceptions for a desired end, generally in practical affairs; acumen may increase with study, and applies to the most erudite matters. Shrewdness is keenness or sagacity, often with a somewhat evil bias, as ready to take advantage of duller intellects. Perspicacity is the power to see clearly through that which is difficult or involved. We speak of the acuteness of an observer or a reasoner, the insight and discernment of a student, a clergyman, or a merchant, the sagacity of a hound, the keenness of a debater, the shrewdness of a usurer, the penetration, perspicacity, and acumen of a philosopher.
