This week in English, we have been looking at prefixes.

Prefixes are a group of letters that change the meaning of a word when they are added to the start.

The prefix un- usually means not, so the new word means the opposite of the original.

For example:

  • unkind means ‘not kind’
  • unhappy means ‘not happy’
  • unlocked means ‘not locked’

Let’s add un-!

Write out the words below adding un- to the start.
Then explain what the new word means.

The first one has been done for you:

1. certain = uncertain
This means not certain

2. sure =

3. happy =

4. tidy =

5. well =

Can you think of any more words you could add un to?


Super Tricky Challenge (only if you want more):

Below is a list of five words you can add un- to.

Choose two words and add the prefix un- to them.

Now write three sentences using those words.

For example: It is unbelievable that you saw an alien!

  • safe

  • zip

  • friendly

  • believable

  • lock
