Answer:
a part added either before or after a root word
Explanation:
The affixes are elements of the language that can appear before or after the root of the word, modifying it and changing its meaning. Affixes can be given two names:
Suffix: It has a morphological function and appears after the root of the word: Ex: Reality, prosperity.
Prefix: It has a semantic function and appears before the root of the word. Ex: Unhappy, insecure.
