I've always refered to it as pluperfect. Maybe it's'because I learnt UK English. Or maybe my teacher was a bit old-fashioned?
I think it has something to do with the way they teach the tenses of romance languages - pluperfect is from the Latin, and when I learned French (and Latin, and German, and Greek, come to think of it) we always referred to it as pluperfect.
I have no idea what we referred to the English tenses as, because this wasn't really taught. Everything I know about English grammar I know from analysing it to learn foreign languages.
As for my WIP, I'm relating the dream of my MC after he woke up. I've tried using the preterit for a flashback scene, but as it's'more a remembrance of a part of his life, it doesn't work too well. Would it work this way?
Eric woke up. His past had resurfaced in his dreams.
When his parents died, his relatives hired a lawyer. And so on
I had no idea what 'preterit' meant until I looked it up - Aorist. Ok, that's a term I understand. Used that all the time in Greek.
I think that would work fine.
You can also use the "had" once to indicate the tense and then leave it out, e.g.:
The bold indicates the entry and exit into the flashback, using "had", but once you're in there you can just carry on in normal past tense.
Yes, I've always nagged people I beta for to get rid of as much pluperfect as humanly possible, especially in extended recollections - I call it 'excessive hadding' and it just gets so boring and repetitive after a few sentences. Use plupf to transition in, change to simple past tense, plupf to transition out. Simples
