Of native Korean origin.
- (Sentence-final particle for verbs and adjectives in the 해요체 (haeyoche, “polite”) speech level)
Usage notes 
In the 해요체 (haeyoche, “polite”) speech level, there is no explicit marker to distinguish between indicative, interrogative, imperative, and hortative moods. The mood distinction is made with punctuation (e.g. “?”, “!”) and pitch (e.g. rising for interrogative) only.
