“Understanding” has 3 distinct senses listed in this dictionary. The most common is: the mental grasp of what something means or how it works.

Knowledge is having information — facts, data, or details you have learned. Understanding goes deeper: it is grasping what those facts mean and how they connect. You can know that a formula exists without understanding why it works. Understanding turns isolated knowledge into a meaningful, usable grasp of a subject.

Not directly. A teacher can present facts, explanations, and examples, but understanding has to be built by the learner as they make sense of the material. This is why two students given the same lesson can reach very different depths of understanding. Good teaching creates the conditions for it to form.

Besides mental grasp, understanding can mean an informal agreement — 'we reached an understanding' signals a shared arrangement rather than a formal contract. As an adjective, it describes someone sympathetic and tolerant, as in an understanding friend. All three senses share the idea of appreciating another person or situation.
