This document discusses different ways that new words can be created, including through acronyms, blending, and derivation. It notes that true coinages are rare and that new words must conform to a language's phonological and morphological rules. Acronyms are formed from the initial letters of words and can become lexicalized over time, such as HIV and laser. Backronyms are created by retrofitting an acronym's letters to real words. While word creation happens, most new words are formed based on existing linguistic elements in a language.
