Pred. nom.

This is a very much simplified listing, but perhaps it will get 
someone started. It does not cover every contingency, but I think 
it is generally accurate.

3 rules for determining the subject with linking verbs when there 
are two nominatives (stated or implied):

1. If one substantive is a pronoun (except interrogative pronoun), 
   it is the subject. This is true even if the pronoun is not 
   explicitly stated but is inherent in the verb.
2. If one of the substantives has an article or is a proper name, 
   it is the subject.

3. If #2 is ambiguous, the nominative first in word order is 
   usually the subject.
