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.
The root word joy can change to become joyful, enjoy and enjoyable.
The root word friend can change to become friendly, befriend and friendship.
The root word play can change to become playful, replay and player.
