Word to the Wise: Perspicacity
by ETR (05/5/2008)
Perspicacity (pur-spih-KAS-ih-tee) - from the Latin for "sharp-sighted" - is acute perception, discernment, or understanding.
Example (as Michael used it today): "You’ve got to like a guy who thinks the way you do. You’ve got to admire his intelligence. Praise his perspicacity."
