This document discusses prefixes, suffixes, and other methods used to form new words in English. It provides examples of prefixes that make words negative, opposite, pejorative, related to time/order, or quantity/position. Suffixes are also explained for forming nouns, adjectives, adverbs, and verbs. Other word formation methods covered are neo-classical affixes, acronyms, clipping of words, and blends that combine parts of multiple words. A variety of examples are given to illustrate each word formation technique.
