So basically, what I am asking about here is if 'had' could actually be the past tense of 'has' and if it could stand alone even without the other past action.
She had suffered enough/ She had been waiting for years until you came. ( the 'has' was replaced with 'had'. Can I use this one? I've been meaning to use it this way.)
She had suffered enough before you came. ( past perfect )
You see, I'm trying to write a story. I'm narrating things that happened in the past so I wanted everything to be in the past tense including 'had'. But my teacher told us that if we used 'had', then it should be with another past action.
Please help me. Thank you.
Oh, I see. Thank you so much!
