what are neologisms

In linguistics, a neologism is any relatively recent and 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 social institutions.

Neologisms are often driven by changes in culture and technology. Popular examples of neologisms can be found in science, fiction (notably science fiction), films and television, branding, literature, jargon, cant, linguistics, the visual arts, and popular culture.

Neologisms are often formed by combining existing words (see compound noun and adjective) or by giving words new and unique suffixes or prefixes. Neologisms can also be formed by blending words, for example, "brunch" is a blend of the words "breakfast" and "lunch", or through abbreviation or acronym, by intentionally rhyming with existing words or simply through playing with sounds. A relatively rare form of neologism is when proper names are used as words (e.g., boycott, from Charles Boycott), including guy, dick, Chad, and Karen.

Neologisms can become popular through memetics, through mass media, the Internet, and word of mouth, including academic discourse in many fields renowned for their use of distinctive jargon, and often become accepted parts of the language. Other times, they disappear from common use just as readily as they appeared. Whether a neologism continues as part of the language depends on many factors, probably the most important of which is acceptance by the public. It is unusual for a word to gain popularity if it does not clearly resemble other words.

The term neologism is first attested in English in 1772, borrowed from French néologisme (1734).[10] The French word derives from Greek νέο- néo(="new") and λόγος /lógos, meaning "speech, utterance". In an academic sense, there is no professional neologist, because the study of such things (cultural or ethnic vernacular, for example) is interdisciplinary. Anyone such as a lexicographer or an etymologist might study neologisms, how their uses span the scope of human expression, and how, due to science and technology, they spread more rapidly than ever before in the present times.

The term neologism has a broader meaning which also includes "a word which has gained a new meaning". Sometimes, the latter process is called semantic shifting, or semantic extension. Neologisms are distinct from a person's idiolect, one's unique patterns of vocabulary, grammar, and pronunciation.

Neologisms are usually introduced when it is found that a specific notion is lacking a term, or when the existing vocabulary lacks detail, or when a speaker is unaware of the existing vocabulary. The law, governmental bodies, and technology have a relatively high frequency of acquiring neologisms. Another trigger that motivates the coining of a neologism is to disambiguate a term which may be unclear due to having many meanings.

Neologism development may be spurred, or at least spread, by popular culture. Examples of pop-culture neologisms include the American alt-Right (2010s), the Canadian portmanteau "Snowmageddon" (2009), the Russian parody "Monstration" (c. 2004), Santorum (c. 2003).

Neologisms spread mainly through their exposure in mass media. The genericizing of brand names, such as "coke" for Coca-Cola, "kleenex" for Kleenex facial tissue, and "xerox" for Xerox photocopying, all spread through their popular use being enhanced by mass media.

However, in some limited cases, words break out of their original communities and spread through social media.[citation needed] "DoggoLingo", a term still below the threshold of a neologism according to Merriam-Webster, is an example of the latter which has specifically spread primarily through Facebook group and Twitter account use. The suspected origin of this way of referring to dogs stems from a Facebook group founded in 2008 and gaining popularity in 2014 in Australia. In Australian English it is common to use diminutives, often ending in –o, which could be where doggo-lingo was first used. The term has grown so that Merriam-Webster has acknowledged its use but notes the term needs to be found in published, edited work for a longer period of time before it can be deemed a new word, making it the perfect example of a neologism.
