Indicates that a past action happened and then immediately changed to another action
When to use
connecting past actions, expressing action change, mid-story transition
The nuance
Attach -(았/었다)가 to the verb stem to indicate that a past action was completed and then immediately changed to another action. It connects two sequential past actions. Examples include 먹었다가 (ate then), 갔다가 (went then), 봤다가 (saw then). It appears in the middle of a sentence, and both actions must be in past tense.
