"Give me _them_ flowers" should be "Give me _those_ flowers"; "I mean
_them_ three" should be "I mean those three." Them is the objective case
of the personal pronoun and cannot be used adjectively like the
demonstrative adjective pronoun. "I am as strong as _him_" should be "I
am as strong as _he_"; "I am younger than _her_" should be "I am younger
than _she_;" "He can write better than _me_" should be "He can write
better than I," for in these examples the objective cases _him_, _her_
and _me_ are used wrongfully for the nominatives. After each of the
misapplied pronouns a verb is understood of which each pronoun is the
subject. Thus, "I am as strong as he (is)." "I am younger than she (is)."
"He can write better than I (can)."

Don't say "_It is me_;" say "_It is I_" The verb _To Be_ of which is is a
part takes the same case after it that it has before it. This holds good
in all situations as well as with pronouns.

The verb _To Be_ also requires the pronouns joined to it to be in the
same case as a pronoun asking a question; The nominative _I_ requires the
nominative _who_ and the objectives _me_, _him_, _her_, _its_, _you_,
_them_, require the objective _whom_.

"_Whom_ do you think I am?" should be "_Who_ do you think I am?" and
"_Who_ do they suppose me to be?" should be "_Whom_ do they suppose me to
be?" The objective form of the Relative should be always used, in
connection with a preposition. "Who do you take me for?" should be
"_Whom_ do, etc." "Who did you give the apple to?" should be "Whom did
you give the apple to," but as pointed out elsewhere the preposition
should never end a sentence, therefore, it is better to say, "To whom did
you give the apple?"
