Definition
忘不了 is a fixed resultative-verb structure: 忘 (to forget) + 不了 (cannot ..., not able to ...). It means 'cannot forget' or 'unforgettable' — you use it when a memory, person, or experience stays with you emotionally. The 不了 here is the potential complement marker showing inability to achieve the result; unlike standalone 忘, which is a simple action, 忘不了 emphasizes that forgetting is not possible.
