Student or Learner
I would greatly appreciate it if you could tell me the definition of 'pluperfect' and 'conjunctive' verbs.
The pluperfect is just another name for the past perfect.
I see him every day - present
I saw him yesterday - simple past
I have seen him before - present perfect
I had seen him around but was still surprised when he came up to talk to me - past present or pluperfect
As for the conjunctive verb, I must leave it to others to answer. That's a new term for me.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
