Roles for EiEnroll

We've been using  EnrollingEntityType  and the element name
enrollingEntity for a while as  the entity that is requesting
enrollment .
My next message will have the jpg diagrams for the
Enrollment-related types for comment.
As I've elaborated the EiEnroll service, this name now ambiguous --
is the EnrollING thing the one that takes the enrollment, or the one
that requests it, or the on that has requested it?
We have parallels in other services (Enrollment is one of several
proposals):
Role
Registration
Enrollment
Tender
Quote
Active/Initiator of request, active in
requesting
Registree
Enrollee
Tenderor
Requestor
Passive in request, active in achieving
Registrar
Enroller
Tenderee
no name
verb infinitive
to register
to enroll
to tender
to quote
I'd like members to make suggestions as to the name(s) to fill the
matrix as consistently and clearly as we can. My thoughts:
Registration and Tender seem unambiguous with common names
thought the  ee  suffix is reversed
Quote::requestor is the  party that requests the quote  and
makes sense as a request. We have no name for  the party that
you ask for a quote from
Enrollment is the harder one--I'm enrollING but I enroll with
whom? An enrollER?! I think that  EnrollingEntity  suggests  the
entity with which you enroll  which reverses the earlier role
description.
Irregular common verbs make this a harder problem.
Thanks!
