This is an incomplete reference that goes back, first of all, to my days
in beginning Greek in the early 1980's.
When we were learning the perfect passive, our instructor (Paul
Kaufmann) handed out copies of an article on "binding" written by either
Dana or Mantey (co-authors of the intermediate grammar used for many
years in many places). Perhaps someone can help me with the details of
the article - I believe I loaned it to someone and didn't get it back,
but it could also be that I've moved about 10 times since then, too. At
any rate, I haven't seen it in my files in a long time.
Perhaps if we can find that article, we will have some suggestions.
