A root is a word part that comes from another language, such as Greek or Latin. An affix is a word part that can be attached to either a root or a base word to create a new word.

4 Affixes Affixes can be divided into two categories: prefixes (appear at the beginning of words) and suffixes (appear at the end of words). Common Prefixes Common Suffixes Bi two -al adjectival suffix Anti against -fy verb suffix Inter between -ic adjectival suffix Pre before -ion noun suffix Super above -ism noun suffix Trans across -ize verb suffix Dis not -ous adjectival suffix
