Perceptive → It is formed from "per-" (meaning through) and "capere" (meaning to seize or take). The word "perceptive" describes the ability to seize or understand things through observation or insight.
Think of someone who can 'seize' ('capere') information 'through' ('per-') their senses — that's why perceptive means having keen insight.
