= Introduction =

An '''apostrophe''' is a small [[Punctuation|punctuation]] mark with two very important jobs in English. It can show that something belongs to someone or something, and it can show that letters are missing in a shortened word. In this aiMOOC, you will learn how apostrophes work with [[Noun|nouns]], [[Possessive|possessives]], [[Plural|plurals]], and [[Contraction|contractions]].

By the end, you should be able to decide where an apostrophe belongs, explain why it belongs there, and edit common apostrophe mistakes in your own writing.

[[File:Apostrophe.svg|220px|frameless|center]]

'''Look closely:''' The apostrophe sits above the writing line. It is not the same as a comma, which sits on the line.

{{BR}}
== Learning Goals ==

You will learn to:
# [[Possessive noun|Use possessive nouns]]: Show who or what owns, has, or is connected with something.
# [[Contraction|Build contractions]]: Replace missing letters with an apostrophe.
# [[Plural|Separate plurals from possessives]]: Avoid adding apostrophes just to make ordinary nouns plural.
# [[Editing|Edit carefully]]: Check confusing forms such as '''its''' and '''it's'''.
# [[Writing|Apply the rules]]: Use apostrophes clearly in sentences, captions, signs, stories, and schoolwork.

{{BR}}
= What Does an Apostrophe Do? =

For Grades 5–6, it helps to remember two main jobs.

{| class="wikitable"
! Job
! What the apostrophe shows
! Example
|-
| Possession
| Something belongs to or is connected with a noun.
| the dog's collar
|-
| Contraction
| One or more letters have been left out.
| do not → don't
|}

[[File:Apostrophe Punctuation Poster.png|500px|frameless|center]]

This video gives a clear overview of apostrophes and explains why the position of the mark matters.

{{#ev:youtube|https://www.youtube.com/watch?v=My6oGvkHnfY|500|center}}

{{BR}}
= Apostrophes for Possession =

A '''possessive noun''' shows ownership, belonging, or a close connection. Possession does not always mean that someone literally owns an object. For example, '''the school's library''' means the library connected with the school.

{{BR}}
== Singular Possessive Nouns ==

A singular noun names one person, animal, place, or thing. To show possession with most singular nouns, add '''apostrophe + s'''.

{| class="wikitable"
! Singular noun
! Possessive form
! Example
|-
| girl
| girl's
| the girl's bicycle
|-
| fox
| fox's
| the fox's den
|-
| teacher
| teacher's
| the teacher's desk
|-
| Maya
| Maya's
| Maya's notebook
|}

A useful test is to reword the phrase with '''of'''. If '''Maya's notebook''' means '''the notebook of Maya''', the apostrophe is showing possession.

{{BR}}
== Plural Possessive Nouns Ending in S ==

A plural noun names more than one. If the plural already ends in '''s''', place the apostrophe '''after the final s'''.

{| class="wikitable"
! Plural noun
! Possessive form
! Meaning
|-
| dogs
| dogs'
| belonging to several dogs
|-
| players
| players'
| belonging to several players
|-
| teachers
| teachers'
| belonging to several teachers
|}

Compare these:
'''the player's shoes''' = the shoes of one player.
'''the players' shoes''' = the shoes of several players.

{{BR}}
== Irregular Plural Possessives ==

Some plural nouns do not end in '''s'''. Examples include '''children''', '''men''', and '''women'''. To make these possessive, add '''apostrophe + s'''.

{| class="wikitable"
! Irregular plural
! Possessive form
! Example
|-
| children
| children's
| the children's games
|-
| men
| men's
| the men's jackets
|-
| women
| women's
| the women's team
|}

{{BR}}
== Shared and Separate Possession ==

When two people share one thing, the possessive ending usually goes on the final name: '''Lena and Ava's project''' means one project shared by Lena and Ava.

When each person has a separate thing, both names can be possessive: '''Lena's and Ava's projects''' means Lena has a project and Ava has a project.

[[File:The Power of the Apostrophe Possession vs. Contraction.png|500px|frameless|center]]

Here is another explanation focused on possessive nouns.

{{#ev:youtube|https://www.youtube.com/watch?v=EXJLYYameBY|500|center}}

{{BR}}
== A Note About Singular Names Ending in S ==

For a singular name ending in '''s''', many school and publishing styles add '''apostrophe + s''', as in '''James's backpack'''. Some style guides allow forms such as '''James' backpack'''. Follow the style your teacher or school uses, and stay consistent.

{{BR}}
= Apostrophes in Contractions =

A [[Contraction|contraction]] joins words in a shorter form. The apostrophe stands where letters have been removed.

{| class="wikitable"
! Full form
! Contraction
! Missing letters
|-
| do not
| don't
| o
|-
| cannot
| can't
| no
|-
| I am
| I'm
| a
|-
| we are
| we're
| a
|-
| they have
| they've
| ha
|-
| it is
| it's
| i
|}

A contraction should keep the meaning of the original words. Try expanding the contraction when you check your writing. If '''it's''' can be replaced by '''it is''' or '''it has''', the apostrophe is correct.

{{BR}}
= Its and It's =

'''Its''' is a possessive [[Pronoun|pronoun]] form. It shows belonging and has '''no apostrophe''': '''The bird spread its wings.'''

'''It's''' is a contraction. It means '''it is''' or '''it has''': '''It's raining.''' '''It's been a long day.'''

Use the expansion test:
'''It's cold''' → '''It is cold''' works.
'''The dog wagged it's tail''' → '''The dog wagged it is tail''' does not work, so the correct form is '''its'''.

Other possessive pronouns also do not use apostrophes: '''his, hers, ours, yours, theirs'''.

{{BR}}
= The Plural Trap =

An apostrophe does '''not''' normally make a regular noun plural.

{| class="wikitable"
! Meaning
! Correct
! Incorrect
|-
| more than one apple
| apples
| apple's
|-
| more than one book
| books
| book's
|-
| more than one teacher
| teachers
| teacher's
|}

'''Apple's''' means that something belongs to one apple, while '''apples''' simply means more than one apple.

Apostrophes are sometimes used in the plurals of single letters when they make reading clearer, as in '''Mind your p's and q's'''. This is a special case, not the rule for ordinary plural nouns.

[[File:Greengrocers' apostrophe 1.JPG|500px|frameless|center]]

This real-world photo shows apostrophes added where ordinary plurals were intended. Mistakes like these are often nicknamed '''greengrocers' apostrophes'''.

{{BR}}
= Spotting and Fixing Errors =

When you are unsure, ask two questions.

{| class="wikitable"
! Check
! Question to ask
! Example
|-
| Possession check
| Does something belong to or connect with a noun?
| the rabbit's hutch
|-
| Contraction check
| Are letters missing from a longer expression?
| we're = we are
|-
| Plural check
| Does the word only mean more than one?
| rabbits
|}

If the word is only a regular plural, it usually needs no apostrophe.

[[File:Grammar error apostrophe.jpg|500px|frameless|center]]

The sign in this photo uses an apostrophe where a normal verb form was needed. Real signs can be useful editing practice because punctuation errors can appear anywhere.

{{BR}}
= Meaning Changes When the Apostrophe Moves =

Apostrophe placement can change meaning.

{| class="wikitable"
! Phrase
! Meaning
|-
| the student's folder
| the folder of one student
|-
| the students' folder
| the folder used by several students
|-
| students
| more than one student
|}

Reading the whole sentence matters. Good punctuation helps your reader understand who owns what and whether a word has been shortened.

{{BR}}
= Strategy for Editing Your Work =

Use this quick decision routine whenever you see a noun ending in '''s''' or a short form that might need an apostrophe.

# [[Possession|Check for possession]]: Decide whether the phrase shows belonging or connection.
# [[Plural|Check the number]]: Decide whether the owner is singular, a regular plural ending in s, or an irregular plural.
# [[Contraction|Expand contractions]]: Replace the short form with its full words to see whether the sentence still makes sense.
# [[Proofreading|Read again]]: Make sure you did not use an apostrophe just to make an ordinary plural.

An apostrophe can show { possession } when something belongs to or is connected with a noun. A singular possessive usually adds { apostrophe plus s } to the noun. A regular plural that already ends in s usually adds an apostrophe { after the final s }. An irregular plural such as children forms the possessive as { children's }. In a contraction, an apostrophe stands for { missing letters }. The word it's can mean { it is }. The possessive form its has { no apostrophe }. An ordinary regular plural such as books usually needs { no apostrophe }.
