in english language there are 3 past tenses. past tense with did or second form, past tense with have and past tense with had.
when i have to use each of them i searched on the internet and i didn't find nothing. can anyone explain me?
you can use that in a sentence properly, for example...
"I did not realize what I had before I lost it."
or you could replace the word "did" with "done", for example...
"I had no remorse for what was done yesterday."
...not sure if this was helpful, if not i apologize. i may not have understood the question.
