The apostrophe has two uses:
To show that a word has been shortened, simply insert the apostrophe where the letters are missing:
- can’t for cannot
- could’ve for could have
- it’s for it is.
Note: these kinds of abbreviation should really only be used in writing when you are using direct speech, words actually said by someone.
A brightly lit neon sign at a holiday camp: Telephone’s X
Sign in shop: Turnip’s for sale X
And worst of all...
Robert Burn’s X
The problem is the s, isn’t it? See an s and hit it with an apostrophe. Please don’t!
If all you want to do is show that there is more than one thing (a plural) just add an s, not an apostrophe.
One turnip Two turnips
One telephone Three telephones
Apostrophes are only used when there is an s that shows something belongs to someone.
Many people know vaguely that the apostrophe goes after the s for a plural (more than one) but then wonder about unusual plural words like children or men which do not have an s.
The girls top was red (note it says 'was' so there is only one top and one girl in it.)
Turned round: The top belonging to the girl.
The trick: the last letter of the last word is l – so put the apostrophe after the l.
The answer: The girl’s top was red.
The two girls tops were red.
Turned round: The tops belonging to the two girls.
The trick: the last letter of the last word is s – so put the apostrophe after the s.
The answer: The two girls’ tops were red.
I collected the childrens books.
Turned round: I collected the books belonging to the children.
The trick: the last letter of the last word is n – so put the apostrophe after the n.
The answer: I collected the children’s books.
What about names which end in s? Do you add another s?
The good news is that it is acceptable to write names either way. One syllable names sound better without the extra s
The poetry belonging to Burns. It needs an apostrophe because it’s not just his name.Two syllable words can take an extra s or not:
Silas’ book or Silas’s book.
Some words end in s and might look as if they should have an apostrophe, but actually they are being used as an adjective to describe something.
The supper doesn’t belong to Burns so it does not need an apostrophe. The word Burns describes what sort of supper it is. This makes it different from Burns’ poetry because the poetry does belong to Burns.
Sometimes its has an apostrophe and sometimes it doesn’t.
