Watch the video and read on for a spelling test and word search.



We can change the meaning of a word by putting a little word called a prefix in front of the word. Prefixes are so important to know because they will not only help your spelling but your reading and vocabulary too

A lot of prefixes change the meaning of the word to the opposite meaning:
happy - unhappy,  legal - illegal, like- dislike , patient - impatient,  correct - incorrect.

There are hundreds of prefixes, some of the most popular are:
in-, ir-, il-, im-, un-, dis-, pre-, ex-, anti-, uni-, bi-.

Recognizing and understanding prefixes will help your spelling and reading.

Test your prefixes

Add a prefix to the following to make the opposite.

1. happy    2. like   3. legal   4. kind.   5.patient    6. regular   7. fair    8. comfortable



Answers
1. unhappy 2. dislike 3. illegal 4. unkind 5. impatient 6. irregular 7. unfair 8. uncomfortable

There are some patterns which help us to know which prefix to add to which word but like all rules there are exceptions.

* use il- before words starting with l    legible - illegible

* use ir- before words starting with r   relevant - irrelevant

* use im- before words stating with m, p and b    
mature-immature, perfect - imperfect, balance - imbalance
