Root words are words that do not have a prefix (letters which can be added to the beginning of a word) or a suffix (letters which can be added to the end of a word). They are words in their simplest form.
For example: joy, friend and play are all root words.
We can add prefixes or suffixes to root words to change the meaning of words and create 'word families'. 'Word families' are words which all have the same root word.
Prefixes and suffixes change the meaning of words.
In this activity, we are going to look at the prefix in.
The prefix in changes the root word to mean either 'not' or 'in/into'.
For example, inactive means not active and inject means to introduce a drug into the body.
Let's make a start on the questions now.
