Further Explanation:
Many students often make a mistake with the correct use of apostrophes. They can be quite confusing, right? Apostrophes can be used for different purposes. Let's take a closer look at them.
1. Apostrophes for contractions
Apostrophes are used for contraction, when we want to shorten a verb form.
Auxiliary verbs - In a positive sentence, when an auxiliary (verb BE, HAVE, WILL) is placed next to the pronoun, the short form is usually used, e.g. I'm/ We're/ He's/ They'llNegative forms - negative forms of auxiliaries are often shortened with an apostrophe, e.g. haven't/ won't/ aren't
2. Possessive 's
Apostrophe is always used to show possession, or that something belongs to someone. Use an apostrophe + s after a name of a person or a thing to show that someone/something belongs to them.
e.g. Megan's sister
Tim's car
If the name of a person ends in s, the apostrophe comes at the end.
e.g. Ross' book
If a plural noun ends in s, we use the apostrophe at the end of the word
e.g. parents' bedroom
boys' room
