Prefix un informs elementary school children that the root word stays the same but the meaning can be changed by this prefix.

Sometimes we can say the opposite of something by adding the letters ‘un’ to a word. If I’m not happy, I can say I’m ‘unhappy’ – the word ‘un’ is added to the beginning of the word to show that I’m not happy. See if you can get full marks on these words that can start with the prefix ‘un'.
