L.C. To understand the terms 'root word' and 'prefix'.

A root word is a part of the word that can stand on kits own.

A Prefix is a few letters that can be added to the root word to create a new word.

Here are some examples of Prefixes:

un, dis, mis, re, im, il 

Lets have a look at the root word : happy.

Which of the prefixes above could we add to the start of our root word to make a new word? There is only 1 that makes sense. 

Unhappy

What has happened to the meaning of the word happy?

The meaning of the word has become the opposite.

Add the Prefix un to the following words and see what happens to the meaning of the words:

friendly

likely

usual

pleasant

helpful

well

Hopefully you will have noticed that they all mean the opposite. This is because the Prefix 'un' means not and makes the word the opposite of the root word.

Lets have a look at another Prefix.

im

Add this prefix to the following words. think about what this Prefix does to the meaning of the root word. 

mature

polite

patient

moral

You should have noticed that again they all mean the opposite. This is because the Prefix 'im' means not and makes the word the opposite of the root word.

However not all Prefixes mean the opposite.

Task go onto Purple mash and complete the English 2do's.
