Perspicuous is based on Latin perspicere, meaning "to see through," so that which is perspicuous is clear and understandable. Perspicuous has a close cousin, perspicacious , which is used of a person with astute insight. Both words come directly from Latin adjectives that mean the same thing they do: perspicuous from perspicuus, and perspicacious from perspicax. Needless to say, it's possible to confuse the two. One easy way to keep out of trouble is to think of perspicUous as the "U" word, and remember that it means "Understandable"—in contrast to the "A" word, perspicAcious, which means "Astute."
