How it's used

Adding this particle at the end of a sentence functions as a strong assertion, signaling to the listener that the speaker is certain about the information provided. It often carries a reassuring or persuasive tone, effectively softening the delivery of a statement while simultaneously reinforcing its truth. When used in questions, it expresses a desire for confirmation or a sense of disbelief regarding the situation.

Examples

Don't worry, I will definitely get it done.

Common mistake

Learners often confuse this with the possessive particle 嘅, which is written with the same character but functions differently. While the possessive particle links nouns, this sentence-final particle serves as a modal marker to convey the speaker's attitude or confidence level.
