Did You Know?

All three denote being acute in perception and sound in judgment, but shrewd stresses practical, hardheaded cleverness, whereas perspicacious implies unusual power to see through and comprehend what is puzzling or hidden. Astute suggests both shrewdness and perspicacity, as well as diplomatic skill.
