Book-learnings refer to the knowledge that is gained through academic sources such as books, lectures, and seminars. The term can also be used to describe a person who relies solely on book knowledge and lacks practical experience. Antonyms for book-learnings include practical knowledge, hands-on experience, real-world experience, and street smarts. Practical knowledge is the experience-based knowledge that one acquires in a specific field, and it differs from theoretical knowledge. On the other hand, hands-on experience involves actively participating in a task or project and learning from the experience. Real-world experience refers to the knowledge that one accumulates through life experiences, while street smarts is the ability to judge people, situations, and make good decisions in everyday life.
