Syn. — To discern; distinguish; observe; see; feel; know; understand. — To Perceive, Discern. To perceive a thing is to apprehend it as presented to the senses or the intellect; to discern is to mark differences, or to see a thing as distinguished from others around it. We may perceive two persons afar off without being able to discern whether they are men or women. Hence, discern is often used of an act of the senses or the mind involving close, discriminating, analytical attention. We perceive that which is clear or obvious; we discern that which requires much attention to get an idea of it. "We perceive light, darkness, colors, or the truth or falsehood of anything. We discern characters, motives, the tendency and consequences of actions, etc." Crabb.
