Guessing & Possibility · How could...?; Is it possible that...?; It cannot be so.
The grammatical pattern V+(으)리오 is a rhetorical question ending used to express the speaker's strong conviction that a particular action or state is impossible or highly improbable. It functions not to seek an answer, but to emphasize the speaker's disbelief, resignation, or challenge regarding the possibility of something. This expression carries a formal, literary, or somewhat archaic nuance.
V+(으)리오 is employed when the speaker wants to convey that something is beyond the realm of possibility or extremely unlikely. The question posed is rhetorical, meaning the speaker already knows the answer (it's impossible) and uses the question to highlight this impossibility to the listener or to themselves. It can express:
The conjugation of V+(으)리오 depends on the final sound of the verb stem:
For verb stems ending in a consonant: Add -으리오.
For verb stems ending in a vowel or the consonant 'ㄹ': Add -리오.
V+(으)리오 shares a similar function with other rhetorical question endings like -겠는가 or -을 수 있겠는가, but it often carries a more profound, dramatic, or poetic tone. While -겠는가 can also express doubt or impossibility, V+(으)리오 tends to be stronger in its assertion of impossibility and is less common in contemporary spoken Korean. The implied answer to a V+(으)리오 question is always a definitive "no" or "it is impossible." Its usage can make a statement sound more impactful and reflective, often used when contemplating a difficult situation or an unchangeable fate.
