In linguistics, a neologism (niːˈɒlədʒɪzəm; also known as a coinage) is any relatively recent or isolated term, word, or phrase that nevertheless has achieved popular or institutional recognition, and is becoming accepted into mainstream language. Most definitively, a word can be considered a neologism once it is published in a dictionary. Neologisms are one facet of lexical innovation, i.e. linguistic phenomena that introduce new terms and meanings into a language's lexicon. The most precise studies into language change and word formation, in fact, identify the process of a "neological continuum": a nonce word is any single-use term that may or may not grow in popularity; a protologism is such a term used exclusively within a small group; a prelogism is such a term that is gaining usage but still not mainstream; and a neologism has become accepted or recognized by linguistic institutions.
Neologisms are often driven by changes in culture and technology. Popular examples of neologis
