we are going to take a look at how to say that you “have to” or “should” do something in Korean.
The construction itself is quite simple to understand. You take the verb stem of a verb and add the part (a verb ending) that makes the sentences take the meaning of “have to” or “should”.
to have to, should, must= verb stem + -아/어/여 (-a/eo/yeo) + -야 되다/하다 (-ya dwida/hada)
Examples:
자다 [ja-da] = to sleep
