"Astute" is similar in meaning to "shrewd" and "sagacious," but there are subtle differences in connotation among them. All three suggest sharp thinking and sound judgment, but "shrewd" stresses practical, hardheaded cleverness and judgment ("a shrewd judge of character"), whereas "sagacious" implies wisdom and foresight combined with good judgment ("sagacious investors"). "Astute," which derives from the Latin noun "astus," meaning "craft," suggests cleverness, mental sharpness, and diplomatic skill ("an astute player of party politics").
