3.3.1. The time representation of the past perfect form
The past perfect form (PaPF) is the compositional form like the present perfect form (PrPF).
This has two meanings, one is the past form of PrPF, the other is the more past of the past tense. See the following time representation.
M is put between E and S, because M is determined after S and E is determined after M. This from has these relationships. (*14)
