The grammar pattern V + 을/를 리가 없다 is used to express strong disbelief or incredulity regarding what has happened, is happening, or will happen.
The term 리 comes from the Hanja 理, which signifies 'logic,' 'reason,' or 'possibility.'
This structure is particularly useful for expressing strong disbelief or impossibility about something, usually in a negative sense.
In other words, it allows you to stress that something simply cannot or could not have happened according to logic or reason.
Understanding how to use 을 리가 없다 will help you articulate disbelief or emphasize the impossibility of certain situations, thereby making your speech more nuanced and expressive.
