Affixes: Understanding Prefixes, Suffixes, and Root Words

Understanding affixes is an important part of developing vocabulary and decoding unfamiliar words in English. Affixes are word parts that are added to a base word or root to create a new word with a different meaning.

Types of Affixes

There are two main types of affixes: prefixes and suffixes.

Prefixes: Prefixes are added to the beginning of a word and change the meaning of the word. For example, the prefix "un-" added to the word "happy" creates the word "unhappy," which means not happy.
Suffixes: Suffixes are added to the end of a word and also change the meaning of the word. For example, the suffix "-ful" added to the word "joy" creates the word "joyful," which means full of joy.

Root Words

Root words are the main part of a word to which prefixes and suffixes can be added. They are the core of the word and carry its main meaning. For example, the root word "act" can have the prefix "re-" added to create the word "react" or the suffix "-ion" added to create the word "action."
