Continuing our series on punctuation for beginners, this post is all about apostrophes.
Welcome to the eleventh post in the series: Punctuation For Beginners.
Today, I will be writing about The Apostrophe.
What are apostrophes?
An apostrophe is a punctuation mark (‘) that is used to indicate either possession (Sam’s car; girls’ hats) or the omission of letters or numbers (won’t; she’s; 22 Feb. ’89).
1. Use Apostrophes To Indicate Possession
Use an apostrophe to show that a thing or person belongs or relates to someone or something.
Example: Instead of saying ‘the storm of yesterday’, we can write ‘yesterday’s storm’.
How to use the possessive apostrophe:
- With singular nouns or most personal names. Add an apostrophe plus s. Example: They met at Tom’s party.
- With personal names that end in s. Add an apostrophe plus s if you pronounce an extra s when you say the word out loud. Example: Thomas’s mother left. (Exceptions to this rule occur, especially in names of places or organisations. Example: St Thomas’ Hospital) Tip: If you aren’t sure about how to spell a name, look it up.
- With personal names that end in s but are not pronounced with an extra s. Add an apostrophe after the s. Example: The judge dismissed the Peters’ appeal.
- With a plural noun that already ends in s. Add an apostrophe after the s. Example: The old house was converted into a boys’ school.
- With a plural noun that doesn’t end in s. Add an apostrophe plus s. Example: The children’s mother lives in Cape Town.
Note: We do not need an apostrophe with the possessive pronouns: his, hers, ours, yours, theirs (meaning ‘belonging to him, her, us, you, or them’).
2. Use Apostrophes To Indicate Omission
An apostrophe can be used to show that letters or numbers have been omitted. These are also known as contractions.
Here are some examples:
- you’re – short for you are
- she’ll – short for she will
- he’d – short for he had or he would
- it’s cold – short for it is cold
- o’clock – short for of the clock
- ’tis – short for it is
- Cash ’n Carry– short for Cash and Carry
Contractions are considered informal, and should not be used in official business documents, contracts, theses and dissertations, formal letters, CVs, forms or applications.
However, you should use contractions in fiction and in most copywriting.
Commonly Confused: It’s Or Its?
its (without an apostrophe) means ‘belonging to it’
- The cat cleaned its ears.
- Each project is judged on its presentation.
it’s (with an apostrophe) means ‘it is’ or ‘it has’
- It’s hot in December.
- It’s a new phone and it’s got some interesting features.
Apostrophes And Plurals
The general rule is that we should not use an apostrophe to form the plurals of nouns, abbreviations, or dates made up of numbers: just add s (or -es, if the noun in question forms its plural with ‘es’).
It’s important to remember this rule. An apostrophe should never be used to form the plural of ordinary nouns, names, abbreviations, or numerical dates.
- You can use an apostrophe to show the plurals of single letters. Example: I have dotted the i’s and crossed the t’s.
- You can use an apostrophe to show the plurals of single numbers. Example: Look for the number 9’s.
These are the only cases in which it is considered acceptable to use an apostrophe to form plurals.
