Five Ways to Use "S"
1. Use "s"or
"es" to show
plurality in countable nouns. You need to show plurality when you are talking
about more than one or are speaking
in general terms about all of the items in one category.
2. Use "s" for present tense subject/verb agreement. Add "s" on the
end of a verb in present tense to agree with the singular "he," "she,"
or "it" subject .
3. Use an apostrophe followed by "s" ('s)
to show that a singular noun belongs to someone or something.
4. Use an "S" followed by an apostrophe
(s') to show possession of plural nouns or
nouns that always end in "s."
The proper noun, Les, always ends in "s."
Notice the apostrophe is added after the s.
For proper nouns ending in "s," it is also accepted
to add 's (Les's book).
5. The word "is" is often abreviated
(or "contracted") in English. Use an apostrophe followed by an "s"
('s) in order to show the contraction for
the word "is."
"IT'S" is simply a shorter way
of saying IT IS. There are several other words that are commonly used with
's to show a contraction. For example, who's,
what's, where's, there's, he's, she's, etc.
