Roots and Affixes

Be sure to look at the bottom of this page for related websites and some resources you can download right from here.






When you are trying to figure out the meaning of an unfamiliar word, it helps to try to break down the word into smaller parts. These parts are called affixes and root words. Affixes include two different types of word parts: prefixes and suffixes. They attach to root words and change their meanings. Prefixes and suffixes provide clues that help define the meaning of a word.


Prefixes are letters added to the front of a root word to change its meaning.

For instance, if I add the prefix “sub” to a word, it changes the meaning of that word to mean “below”   Substandard, then, means below standard.


Suffixes are letters added to the end of a root word to change its meaning.

“ful” for example, is a suffix meaning “filled with.” The word ‘frightful’ means filled with fright.

Most modern English words come from other languages. There are many, many root words but I have selected some of the most common Greek and Latin roots. Becoming familiar with these roots will be a great help when we read for understanding!
