Introduction to apostrophes

Apostrophes may be small but they play a vital role in clarifying information within a sentence. It can be very easy to misuse apostrophes in your writing so follow these rules in order to conquer those common mistakes.

  • Apostrophes are used for two main jobs, showing and showing .

  • Apostrophes for possession show that a thing belongs to someone or something. For example Anna鈥檚 book or the school鈥檚 logo.

  • Apostrophes for omission show where something, usually a letter, has been missed out to create a . For example, haven't rather than have not.

Apostrophes for possession

For most nouns you just need to add an apostrophe and an s to show that something belongs to a person or thing. It's a handy tool because instead of saying the bedroom of Luca, the apostrophe and the s make it Luca鈥檚 bedroom. Much easier!

Here are some more examples: the 蝉迟耻诲别苍迟鈥檚 bravery, the 丑别补诲迟别补肠丑别谤鈥檚 assembly, the 迟别补尘鈥檚 performance.

When the noun is plural and already ends in s, move the apostrophe to the end, like this: the 蝉迟耻诲别苍迟蝉鈥 behaviour or 诲补苍肠别谤蝉鈥 routines. Putting the apostrophe at the end means that we know there are multiple students or many dancers being referred to.

Apostrophes for omission

Omission means leaving something out, and we often do this with letters or groups of letters in words. The apostrophe shows where this has happened.

Sometimes we join two words together, like would've for would have. This is known as a contraction and the apostrophe in this case shows where the letters ha have been removed.

Examples of contractions

I am滨鈥檓
you are测辞耻鈥檙别
we will飞别鈥檒濒
he is丑别鈥檚
she had蝉丑别鈥檇
who is飞丑辞鈥檚
can not肠补苍鈥檛
will not飞辞苍鈥檛
let us濒别迟鈥檚

It鈥檚 or its?

These two words cause confusion because they break the rules! Here鈥檚 what you need to remember: it鈥檚 with an apostrophe means 'it is' or 'it has'. In the sentence "It鈥檚 a good idea" it works just like an ordinary contraction.

But its (without an apostrophe) means 'belonging to it鈥, the bird spread its wings. The reason 'its' doesn鈥檛 need an apostrophe is because it is a . Like other possessive pronouns (hers, his, yours, theirs) an apostrophe is not required as they already indicate possession without an apostrophe.

Choose it's or its

Common mistakes

One of the most common mistakes that people make when it comes to apostrophes is using them in plurals ending in an 鈥榮鈥. For example, we are open Monday鈥檚 to Friday鈥檚. In order to pluralise a regular noun all you usually need is to add an 鈥榮鈥. Therefore, the correct version is we are open Mondays to Fridays.

Similarly, apostrophes are not needed in abbreviations like DVDs or HGVs. This same rule also applies when using numbers like the 1920s or the over 60s.

Another common mistake is forgetting that the contractions 'should鈥檝e', 'would鈥檝e' and 'could鈥檝e' are shortened versions of 'should have', 'would have' and 'could have'. The clue is in the endings: 've' comes from 'have' not 'of' but people often make this mistake because the letter sounds are so similar.

Key points

Remember

It's always worth checking the apostrophes in a piece of writing, as missing one 鈥 or adding one that isn鈥檛 needed 鈥 is the most commonly made punctuation mistake.
