GRAMMAR
should be obvious that you wouldn't say me was hauled off for
interrogation.
Sentence 4 is trickier: Here, it is less easy to recognize the pronoun
as a subject because it is not followed by any verb. This is an example
of an elliptical construction (see the discussion on page 85), in that
the verb is implied but not stated. Effectively, this sentence is saying
My brother can crochet better than I can crochet: Thus, the pronoun
is a subject. It is only fair, however, to add that many people
would use me in this type of construction, and some authorities
state that it is permissible or even preferable to do so. You must
determine your own comfort level.
In sentences 5, 6 and 7, the pronoun is me because in each case
it represents the object: something that is acted on or affected by
the subject. An object is not followed by an associated verb, either
explicit or implied. In sentence 5, the pronoun is the target of the
action gave; in sentence 6, it is the target of the action inviting;
in sentence 7, it is the target of the preposition between. In all three
cases, no action or description follows the pronoun.
When there is more than one object, people often think that I
sounds more educated or genteel than me. (Some grammar books
are kind enough to call this type of usage "hypercorrectness." A
better term for it is "wrong.") If you are ever uncertain, mentally
drop any distracting elements. It should be obvious that you wouldn't
say The guys gave I or Thank you for inviting I.
Finally, in sentence 8, the pronoun is I if what's meant is Sidney
wanted the job more than I wanted the job (an elliptical construction,
where both Sidney and the pronoun are subjects), and me if
what's meant is Sidney wanted the job more than he wanted me
(both the job and the pronoun are objects). Because of the likelihood
that many readers would not understand this distinction, it would
often be better to fill in the implied words.
PERSONAL PRONOUNS WITH ELLIPTICAL CONSTRUCTIONS
You can apply the same strategies described above to determine
when to use she and her, he and him, we and us, and they and
them. That is, mentally fill in any elliptical constructions or drop
any distracting nouns to help determine whether the pronoun is
acting as a subject or an object.
