Etymology

Origin of insight

First recorded in 1150–1200; Middle English; in- ¹ ( def. ) + sight ( def. )

Explanation

When you have an insight, you have a feeling or emotion or thought that helps you to know something essential about a person or thing. Insight isn't based on hard facts or evidence. And it doesn't have anything to do with using your senses such as sight or smell. When you gain insight, you are using your intuition, or sixth sense. Insight is formed from the prefix in- plus the English word sight, so this word literally means seeing inward.
