Grammatically Correct: The writer's essential guide to punctuation ...

GRAMMAR
that represents the entity that is affected by the action of the subject
is called the object and takes the objective case: For example, Don't
you wait for me. The possessive case is used to indicate ownership,
and differs depending on whether or not the possessed object follows
the pronoun: That's my chair/That chair is mine.
No one would say Me will be late, don't you wait for I, but in
some situations the correct pronoun is not so obvious. This section
looks at a number of constructions that many writers get wrong. It
does not present a comprehensive review, since English speakers
intuitively use the majority of pronouns appropriately.
A word on this topic before beginning. With pronouns, probably
more than any other aspect of English diction, there is considerable
disparity between what the rule books say and how most people
actually use the language. Educated, cultured speakers who
wouldn't dream of saying I can't go no further or he don't sing so
good will readily use pronouns in ways that contravene traditional
grammar, often because they feel that the word that is technically
correct would sound unnatural or overly formal. Or they may choose
to use the "correct" form in formal and academic writing, but go
with common idiom elsewhere. Most modern guides to English usage
recognize this reality and stop short of dictating that every pronoun
rule be followed under every circumstance. This book is no exception.
It is important, however, that you be familiar with the rules so
that if you choose to bend them you do so consciously. Experienced
writers can distinguish between those situations where disregarding
a rule would sound reasonable and those where disregarding it would
sound just plain ignorant. In situations where you don't feel comfortable
using either a stilted-sounding correct pronoun or a more
natural-sounding but incorrect one, it may be best to recast the
sentence.
PERSONAL PRONOUNS
Personal pronouns refer to people and things. The subjective personal
pronouns are I, you, he, she, it, we and they, and the objective
