Root Words

Many words can be formed by adding a prefix to another word. Consider these examples: 


         re + match = rematch

         dis + lodge = dislodge

         un + tangle = untangle
The prefix is the short word part which is added to the root word. It modifies the meaning of the root word. For instance, untangle is the opposite of tangle since "un" means not.
Here are a few more examples: 

         re + search = research

         re + do = redo

         un + do = undo
