Affixes

An element placed at the beginning or end of a root, stem, or word, or in the body of a word, to modify its meaning.

Prefixes come before the root
Suffixes come after the root
Root words, prefixes, and suffixes all have meanings of their own. If you learn to recognize a common root, prefix, or suffix, you can figure out what a new word means without looking up the definition.

Two types- Inflectional and Derivational

Inflectional do not change the word, just the syntax to make it make sense in a special situation. This means changing the tense or the quantity of something, for example, by adding -s, -es, -ing, -ed, etc.

Derivational typically change the word into an adverb or adjective and can effect meaning. They include -ish, -ness, -less, -ian, -ly, etc.
In the summary section of your notes, write at least 10 different words that include at least one affix (prefix or suffix) and a root word. Write the meaning of the word in your own words beside it.
