Usage

This expression is used when the speaker wants to emphasize that a particular action or state is the only logical or possible outcome given the preceding context or reasons. It implies that the subject is forced into a situation or action because all other options are either impossible or unreasonable. It can be applied to both verbs (actions) and adjectives (states).

It is often used when there's a clear, undeniable reason or circumstance that leads to the inevitable conclusion. For example, if someone studies extremely hard, it's inevitable they will do well. If a situation is very difficult, one might have no choice but to give up.

Knowledge Plus

• This expression is similar in meaning to -지 않을 수 없다 (cannot help but, must), but there's a subtle difference.

• It can be used with adverbs like 결국 (eventually), 당연히 (naturally, of course), or 어쩔 수 없이 (unavoidably) to further emphasize the inevitability.
