  4. 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
