Please use apostrophes correctly!

It's (illustrating correct or incorrect use of an apostrophe in written English)

Do not underestimate the difference that using correct grammar will make to your web pages.

No criticism of those who have made mistakes such as those highlighted on this page is intended.

All writers of English text, whether on web pages, SMS text messages, notices or documents of any type, should ensure correct usage of the apostrophe and ideally put right mistakes made inadvertently.

Although some people do not notice incorrect grammar, many people do, especially those who read a lot (whether it is books, articles or press releases) or for whom writing is a part of their job. If a reader notices that you have used incorrect grammar, you will instantly lose credibility.

Do not assume that if you don't know whether to use an apostrophe, then most of your readers won't either.

Many of your readers will notice, and they will infer that you did not learn to write correctly. Whenever you write a plural, a contraction, or a possessive noun you should always check to see whether an apostrophe should be used or not, and that if it is to be used, it is in the correct place.

The rules concerning the use of apostrophes in written English are very simple:

The rules Examples
Apostrophes are used to denote a missing letter or letters it's instead of it is
  I can't instead of I cannot
  I don't instead of I do not
  it's instead of it is

Apostrophes are used to denote possession

the dog's bone
  the council's logo
  Jones's bakery (but Joneses' bakery if owned by more than one Jones)

... but please note that the possessive form of it does not take an apostrophe any more than ours, yours or hers do

the bone is in its mouth

... however, if there are two or more dogs, councils or Joneses in our example, the apostrophe comes after the 's':

the dogs' bones
  the councils' logos
  Joneses' bakeries

Apostrophes are NEVER ever used to denote plurals! Common examples of such abuse (all seen in real life!) are:

Banana's for sale which of course should read Bananas for sale
  Menu's printed to order which should read Menus printed to order
  MOT's at this garage which should read MOTs at this garage
  1000's of bargains here! which should read 1000s of bargains here!
  New CD's just in! which should read New CDs just in!
  Buy your Xmas tree's here! which should read Buy your Xmas trees here!

Note: Special care must be taken over the use of your and you're as they sound the same but are used quite differently:

  • your is possessive as in this is your pen
  • you're is short for you are as in you're coming over to my house
