Dictionary of Problem Words and Expression
It & Its & it’s & it’s me
It is a short, necessary word
often used in a vague or indefinite way
to stand for, or refer to,
a variety of things and ideas.
The term also appearsin expression
that are trite or slangy,
such as, “to get with it,”
“be with it,” “have it,” (“be attractive”)
“had it” (“reached the end of endurance or patience”).
Itis a singular pronoun in the third person;
“it don’t” and “it weren‘t” are illiteracies.
Itsis the possessive form of it.
”The dog has lost its collar.”
“I’m sorry about its arriving too late for your birthday.”
It’smeans “it is” (It’s raining) and “it has” (It’sbeen raining).
Awkwardand stiltedthough the expression may sound,
one should say “It’s I” rather than “It’s me”
because a predicate complement is in the nominative case.
If you don’t like to say “It’s I” (or it is I” or “This is I”),
then say “This is” followed by your name.
Similarly, watch out for such expressions
as “It’s us,” “it’s them,” “it’s her,” “it’s him.”
If you think the correct forms of we, they, she, and he,
in these constructions sound strained,
then use names: “It’s Jane,” “It’s Jim.”
Common Errors in English Usage Dictionary
ITS & IT’S
The exception to the general rule
that one should use an apostrophe to indicate possession
is in possessive pronouns.
Some of them are not a problem.
“Mine” has no misleading “s” at the end to invite an apostrophe.
And few people are tempted to write “hi’s,”
though the equally erroneous “her’s” is fairly common,
as are “our’s” and “their’s—all wrong, wrong, wrong.
The problem with avoiding “it’s” as a possessive
is that this spelling is perfectly correct
as a contraction meaning “it is.”
Just remember two points
and you’ll never make this mistake again.
(1) “it’s” always means “it is” or “it has” and nothing else.
(2) Try changing the “its” in your sentence to “his”
and if it doesn’t make sense, then go with “it’s.”
