Clearly expressed; lucid; easy to understand, especially because of clarity and precision of presentation. The quality of being perspicuous is perspicuity. (pron. pr'spik"yoo-es, pr'spe-kyoo"e-tee) Not to be confused with perspicacious. 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," that means "Astute." Both words come directly from Latin adjectives that mean the same thing they do: "perspicuous" is based on Latin "perspicere," meaning "to see through," so that which is perspicuous is clear and understandable. "perspicacious" from "perspicax."
