This is the 13850th most frequent Korean word.
만다
The word "만다" does not exist as a standalone term in standard Korean; it may be a misspelling or require additional context.
In this sentence, '만다' is used as a conjugation of the verb '말다' indicating cessation or stopping of an action.
그는 결국 일을 만다.
He eventually quits the job.
Here, '말고' derived from '말다' is used to convey the idea of 'not doing' something.
만나지 말고 헤어지면 된다.
It's fine not to meet and just separate.
This usage of '만다' again stems from the conjugation of '말다,' referring to stopping a specific activity, in this case, speaking.
