Root Words

A good example of a word containing an interesting root word is: 


   discoloration
You probably recognize the word color in the middle of this word. We only talked about prefixes (like the dis- at the front of discoloration) in this unit, but you will notice that this word also has a suffix added to the end. For your information, a discoloration is more or less, in many cases, the same thing as a stain, although it could be other things too.

Contractions

Recall some of the contraction examples from earlier in this unit. 


   will not --> won't

   let us   --> let's

   do not   --> don't

   can not  --> can't
Most contractions are formed by combining a word like do with not and replacing the o in not with an apostrophe. But as you can see from the list, there are exceptions.
