- 아/어다가
It is added to a stem of an action verb indicating the speaker does a previous action, and then 'does a related action in a row' at the other place with the result of the previous action. Therefore the places where the previous and latter actions happened are different and the subjects of both actions 'are the same. '가' is omitted and is only able to be used as a form of '-아/어다'
