How it's used
Focuses on the sudden realization that something was forgotten, often implying a momentary lapse in memory rather than a permanent loss of information. It carries a slightly more active feel than 唔記得, as if the memory was supposed to be triggered but failed to surface. It is frequently paired with 添 at the end of a sentence to express a sense of realization or mild regret.
Examples
I completely forgot that I needed to hand in my homework earlier.
Did you forget that we have a meeting today?

Common mistake
Avoid using this to describe long term memory loss or general forgetfulness, as it specifically refers to failing to bring a specific fact to mind at a particular moment. Use 唔記得 for general cases where you simply do not have the information in your memory.
