This document discusses the major processes by which new words are formed in the English language. It describes the main processes as affixation, compounding, reduplication, and suppletion. Affixation involves adding prefixes or suffixes to existing morphemes. Compounding combines two or more words to form a new word. Reduplication duplicates all or part of a word. Suppletion changes the form of a word irregularly. Some minor word formation processes mentioned include acronyms, blending, and clipping.
