Expresses experiences or states that happened in the past.
When to use
Recalling past experiences, Describing repeated past situations, Emphasizing states that have ended
The nuance
Attach -(았/었)었던 to verb stems to emphasize past experiences or states. It conveys a more vivid or reflective memory than simple past tense. For example, '가다' becomes '갔었던'. It's suitable for talking about repeated experiences or states that have ended.
