Did You Know?

Perspicacious is similar in meaning to shrewd and astute, but a sharp mind will discern subtle differences among them. All three mean 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.
