Now I'd like to draw your attention to 0109. Take a look at the
second
sentence: "The relationship is an instance of the type of relationship which
is the subject of the node that serves as the T endpoint of the AT arc of
which the a-node is the A endpoint, if any."
There are about 10 layers of nesting in that sentence. I think I know what
it says, but when you string qualifiers onto qualifiers onto qualifiers
(prepositional phrase modified by a prepositional phrase modified by
subordinate clause that contains a subordinate clause . . .), you're going
to lose your readers. Break it up!!
