Roots and Affixes

Affixes are parts of a word that are added to a main word part or root.  The affix changes the meaning of the root word.

There are two types of affixes: prefix and suffix. Prefix occurs before the root. The suffix occurs at the end of the word.

Just remember “PRS” to remember the order of the word parts.
