-아/어/여야 하다
-a/eo/yeoya hada
In Korean, the English phrase "have to" is expressed using the pattern -아/어/여야 하다 (-a/eo/yeoya hada).
This pattern is attached directly to the verb stem to express necessity or obligation.
Meaning: obligation (verb)
What does it mean word for word?
The structure -아/어/여야 하다 literally means "must do [verb] in order to be/to do".
Which one should you use?
While the pattern -아/어/여야 하다 and the pattern -아야 되다 both mean "have to", the latter is much more common in spoken, everyday conversation.
How does it change in a sentence?
The way this pattern changes depends on the context: the polite form ends in -해요 (as in -아/어/여야 해요), and the plain form -아/어/여야 한다 is used in writing, journals or when stating a general fact or rule. To express a past obligation ("had to"), change 하다 to 했다 to form -아/어/여야 했다.
How do you pronounce it?
-a/eo/yeoya hada
Did you know?
- The phrase -아야 하다 is fundamentally linked to the concept of a prerequisite, literally suggesting that if you do not perform the action, the desired result simply cannot 'happen'.
- The verb stem of the modern 하다 is actually a fossilized remnant of the ancient Middle Korean word ᄒᆞ다, which explains why the form 하여 appears so different from its base.
- While -아야 되다 is the norm for casual talk, using -어야 한다 while speaking can signal a high level of formal authority or a legal requirement.
