When we perceive something, we become aware of or notice it. Sometimes we perceive things by using our senses of sight, hearing, and smell.
Or we can use our mind to perceive things, which means that we are able to recognize or understand them. We can also perceive a person or thing as having certain qualities: Do you perceive yourself as a good student? The Latin root percipere means "to receive, understand," from the prefix per- "thoroughly" plus capere "to seize, take."
