Apostrophes
Common
Contractions:
I've = I have
you'd = you would
or
you had
it's = it is
we'll = we will
they're = they are
aren't = are not
can't = cannot
haven't = have not
shouldn't = should not
Use of the apostrophe is tested in two ways in Praxis.
One is its use in
contractions, two words that are
made into one by dropping a letter and replacing it
with an apostrophe.
Pronouns are frequently
combined with forms of the verbs
to be and to have;
modals (words like may, might and should) and the
verbs
to be and to have are often combined with the
word
not.

The two contractions that most often appear
incorrectly in standardized tests are
it’s (it is) used in
the place of the possessive pronoun
its, and they’re
(they are) used instead of
their or there.

Apostrophes are also used to show
possession or
attachment. Singular and plural nouns that do not
end in
s are made possessive by adding an
apostrophe and an s
. Plural nouns, and singular nouns
that end in
s are made possessive by adding an
apostrophe
:

Ashot’s car   clock’s hands   cat’s tail   
men’s room
Jess’ car    clocks’ hands    cats’ tails  
ladies’ room

We often  use the possessive form to speak of time
and amounts.  For example, instead of saying
after
waiting a week
, we more commonly say after a
week's wait
.  

the work of a day   is the same as   a day's work
the salary made in a month
  
is the same as   
a month's salary
the study of two years
  
is the same as   
two years' study

Be especially careful with compound subjects. If
both subjects are attached to or possess that which is
being discussed, both must be in the possessive.
Consider the difference between these two sentences:

Jan’s and Tom’s brothers are rocket scientists.
Jan and Tom’s brothers are rocket scientists.

In the first sentence, the brothers of both Jan and Tom
are rocket scientists; in the second sentence, Jan is a
rocket scientist, and so are the brothers of Tom.

Haruna's hands
move in time with
feet.
Remember!
Make words that do
not end in
s possessive
by adding
's; make
words that end in
s
possessive by adding
'.
Haruna learned a
year's worth of new
dances in only six
months.
A Common Error:
Never use the word
time in combination with
words that express time
as in
a week's time, or a
year's time
. These
words include the idea
of time; adding the
word
time is redundant
(saying something
twice).
