Usage notes

For vowel harmony, contractions, and allomorphy, see 아/어/여 (-a/eo/yeo).
Since 어야 (-eoya) expresses condition or futility, the past tense marker 었 (-eot-) is not used in the second clause.
Similarly to 어서 (-eoseo), 어야 (-eoya) cannot be followed by imperative or propositive clauses.
When 어야 (-eoya) expresses condition, it is most likely to be followed by 하다 (hada) or 되다 (doeda) to express obligation or necessity.
To intensify the meaning of the condition, 만 (-man) and 지 (-ji) are added to 어야 (-eoya).
In the second sense, the suffix is usually accompanied by 아무리 (amuri) or is used in the interrogative construction R어 봐야 얼마나 R겠 (R-eo-bwaya eolmana R-get-).
