Hi All,

Can someone please comment on the following rule. Somewhere I read this:

Is this really the case.

===========================================
Manhattan says which, who and whom, if present immediately after comma, refer to the noun immediately preceding comma, but if comma is not present, this rule doesn't apply.
==========================================

Can someone please tell

a) X of Y, who
b) X of Y who

In the above sentences what does who modifies and why....assuming both X and Y are nouns....which can be properly modified by who individually....
