Please don't say "in past perfect". I know it very well. But I've never understood what it meant to be "perfect". If I can "perfectly" describe any time interval where that incidence of which I am talking about "had" taken place, then it is perfect, right?
But still I'm confused. Please can you help me.
And please notice how weirdly I've used my last "had".

Hi pag161; Welcome to the Forums.

You seem to have mastered the pluperfect tense, but are asking about the definition of "perfect," as in "past perfect."

From the dictionary, posted below is one of the definitions of "perfect." An obsolete meaning of "perfect" is "assured" or "certain," which certainly applies to an action in the past perfect tense. Although the action itself may not have been done correctly, it is certain that it has finished.

Grammar
a.
noting an action or state brought to a close prior to some temporal point of reference, in contrast to imperfect or incomplete action.

pag161But I've never understood what it meant to be "perfect".
In English grammar, "perfect" means composed of has, have, had or having and a past participle. There are so many different uses of grammatical structures called "perfect" that it is impossible to say with any precision what a perfect tense might mean in any given sentence.

What is that temporal point of reference. Nobody told me of this, you are the first person. Thanks!

"how to use" from online english tutorial

Use 1: Completed Actions before something in the past.

e.g. I had never seen such a beautiful beach before I went to Kauai.

Use 2: Duration before Something in the past (non continuous verbs)

e.g. We had had that car for ten years before it broke down.

Actually I write and speak totally different. While speaking I don't care about any grammar rules and so it's very easy for me but while writing I face a lot of problem. I had to take care of every rules taught in my school.

My last sentence "notice how weirdly I've used 'had'.". If I would have spoken this then it's something like this "notice how weirdly I had used my last 'had'. But since I can't make any temporal point in the past so I've to use "have" while writing, and so I'm very incomfortable. Can you throw any light on this.
