How much do you know about apostrophes?
I'm always using them wrong
I know some rules
I mostly use them correctly but occasionally make mistakes
I know everything about apostrophes!
Apostrophes (') can be confusing even for native speakers of English.
 
However, they aren't difficult to master if you remember a few rules.
 
There are two groups of rules for apostrophes:
 
1) Apostrophes used in contractions
2) Possessive  's

APOSTROPHES IN CONTRACTIONS
 
This is a very simple rule: 
 
When you combine two words (typically a personal pronoun and a verb) to make a contraction, you take some letters out and put an apostrophe instead of the deleted letters. 
 
it + is +not = it isn't
let + us = let's
do + not = don't
does + not = doesn't
did + not = didn't
 
they + have = they've
are + not = aren't
they + will = they'll
it + is = it's
She+has+got = she's got
 
He + would+ like =he'd like
I +would + rather = I'd rather
 
They + had + done = they'd done
You + had + better = you'd better
 
 
You can see that usually it's the vowel that is missed out ( is not = isn't) or the beginning of the auxilliary verb (they+had+done = they'd done)
 
One exception to this rule is the contraction "won't" = "will + not."  We didn't just take someting out but also put a new letter in. 
 
Don't confuse this word with "want" which does not have an apostrophe!

Tick the contracted forms with correct apostrophes
It's warm.
They'are late
Iv'e finished.
He's got it.
You'd better take a look.
Shed' rather leave now.
They wont help
He does'nt know
She has'nt started
We didn't do it.
We'd love to help.
I do'nt want this.
You shouldnt of done it.
You'd better take a look at this.
APOSTROPHE RULES FOR POSSESSIVES
 
Let's take a look at the different ways apostrophes are used around possessive words.
 
Use an apostrophe + S to show that something/someone belongs to someone/something
 
Michael's book
 
Lisa's sister
 
Johnson's report
 
My mother's purse
 
The teacher's laptop
 
Snowflake's ball
 
My cat's toys
 
The company's policy
 
 
You can see that we use possessive apostrophe + s after a person's or a pet's name and after a noun indicating a person, an animal or an organisation. 
 
NOTE 1: In modern English it is also considered acceptable to use possessive apostrophe +s with inanimate objects in some contexts: the table's legs; his vehicle's side mirror.  However, if in doubt, use the phrases "the legs of the table", "the side mirror of his vehicle" instead when talking about inanimate objects)
 
 
 
NOTE 2: If a name ends in s ( Ross, Chris, Charles,  Mrs Jones) there are two options to make a possessive form: 
 
We can either add an apostrophe+s at the end: Ross's room, Chris's car, Mrs Jones's house, Dickens' s novels
 
OR
 
We can just add the apostrophe but skip the s: Ross' room, Chris' car, Mrs Jones' house, Dickens' novels.
 
 
NOTE 3: Some natives speakers of English skip the possessive apostrophe after a name or a noun, especially in announcements, adverts or labels. This is a mistake and is NEVER acceptable, not even in informal English! 
 
WRONG:
Bennys Cafe
Bobs Fish
Doctors Surgery 
Mens Toilets
 
CORRECT: 
Benny's Cafe 
Bob's Fish
Doctor's Surgery 
Men's Toilets

APOSTROPHE RULES FOR POSSESSIVE - continued
 
 
Using possessive apostrophes at the end of plural nouns seems to cause many problems, even for native speakers of English. However, this is not tricky at all as long as you remember these two rules: 
 
 
Rule 1: Put an apostrophe AFTER  the plural ending "s" at the end of a plural noun to show possession:
 
My parents' bedroom
The students'  results
The teachers' union
The horses' stables
The Smiths' house
 
It is important to notice the place of the apostrophe to see whether the noun is singular or plural as this changes the meaning of the sentence and the situation.
 
The teacher's notebooks were on the desk.- In this situation there was one teacher with a few notebooks.
 
The teachers' notebooks were on the desk.  In this situation there were a few teachers.
 
 
The farmer knew that the horses' teeth needed to be checked regularly. - In this situation the farmer had a few horses.
 
The farmer knew that the horse's teeth needed to be checked regularly. - In this situation the farmer had one horse. 
 
 
 
 
Rule 2 Some nouns make irregular plurals: man-men, woman-women, child-children, person - people. For these irregular plurals, add an apostrophe + "s" to create the possessive form.
 
My children's school
Women's rights
The people's choice

You're right!
I know that you're all very smart and hard-working.
You're going to pass your exam with flying colous.
 
They're wrong!
I think they're just lazy.
They're are going to realise how wrong they were.
 
 
Your and Their are possessive adjectives ( like his, her, my, its, our)
