This document discusses different types of word coinage in English, including compounds, acronyms, backformations, abbreviations, eponyms, and blends. Compounds are formed by joining two or more words together, but the meaning is not always literal. Acronyms are derived from the initial letters of words. Backformations involve incorrect morphological analysis leading to new words. Abbreviations are clipped forms of words. Eponyms are derived from proper names. Blends are similar to compounds but parts of words are deleted. Examples of each type are provided.
