Greek and Latin Roots/Affixes

What are roots and affixes?

A root is a basic word that is used to create other words.


An affix is a part added to a root word to help in forming other words. Affixes are also known as prefixes and suffixes.


  • a prefix is added to the beginning of a root word
  • a suffix is added to the end of a root word.



For example:


  • the root cred means believe.
  • the prefix in- means not.
  • the suffix -ible means able.


If the root, prefix, and suffix above are combined to form the word incredible what would that word mean?















Answer: Not able to be believed.
