Past: ~(으)ㄴ (Example: 마신 물), Present: ~는 (Example: 마시는 물), Future: ~(으)ㄹ (Example: 마실 물)
Can this phrasing be used as a more general concept, ie "The bulgogi I've eaten was delicious" - that is, in your experience, all the bulgogi you've had is delicious? Or is it only referring to a single serving you had one time?
The former is unlikely, but possible. "The bulgogi I've eaten was delicious." is now accepted. You would say "제가 먹은 불고기는 다 맛있었어요." to refer to all the bulgogi. Also depending on the context, you'd use -던 instead.
It suggested that the correct answer was: "The bulgogi which i'd was delicious."
(For the record, I had typed "The bulgogi which I ate was delicous"
"The bulgogi which I ate was delicious" would be correct. Posted on Dec. 11, 2017.
"The bulgogi which I ate was delicious." is now accepted and the primary translation.
