Apostrophes for short forms

When two words are squashed together, an apostrophe goes exactly where the missing letters were.

The rules

When it's taught at school: Year 2.

  1. 1

    The apostrophe replaces the missing letters

    • do not β†’ don't
    • I am β†’ I'm
    • they are β†’ they're
    • we have β†’ we've
  2. 2

    Some short forms change a little

    • will not β†’ won't
    • cannot β†’ can't
    • shall not β†’ shan't
  3. 3

    Short forms are for chatty writing and speech

    In formal writing, the full words are often better.

    • "I don't know," said Mia.
    • We do not accept late entries.

Common mistakes

  • I didnt finish my homework.

    I didn't finish my homework.

    didn't is short for 'did not': the apostrophe shows where the o was.

  • She is'nt coming.

    She isn't coming.

    The apostrophe goes where the missing letter was: is not β†’ isn't, between the n and the t.
