Common mistake:
Learners sometimes confuse "lesion" with "wound" or "cut" and use it in everyday situations (e.g., saying "I got a lesion" after a minor scratch). "Lesion" is usually used in medical or scientific contexts, often for changes inside the body or for serious skin problems. It is also sometimes confused in spelling with "lesson," which is completely unrelated.
