10. Notice, discern, perceive imply becoming aware of, and paying attention to, something. To notice is to become aware of something that has caught one’s attention: to notice a newspaper headline; to notice a road sign. Discern suggests distinguishing (sometimes with difficulty) and recognizing a thing for what it is, discriminating it from its surroundings: In spite of the fog, we finally discerned the outline of the harbor. Perceive, often used as a formal substitute for see or notice, may convey also the idea of understanding meanings and implications: After examining the evidence he perceived its significance.
