Explanation:

Suffixes are letters that we add after the root of a word (the main part of the word) to form new ones. The addition of the Suffix can change the category of a word. For example, if the root of a word is a noun when we add a suffix it turns into an adjective, like beauty and beautiful.

Prefixes are letters that we add before the root of a word, and as well as suffixes, they can modify the part of speech of a word.
