Definition of «book smart»

"Book smart" is a colloquial adjective phrase used to describe someone who is academically intelligent or well-educated but lacks practical experience or "common sense." It implies a disparity between theoretical knowledge gained from reading and the ability to navigate everyday social or physical situations effectively. The term is often used in a slightly critical or patronizing way to explain why a highly qualified person might make obvious mistakes in real-world scenarios. It contrasts directly with being "street smart," which prioritizes intuition and practical problem-solving.
