The word neologism derives from Greek roots, formed from “neo” which means “new” and “logo” or “λόγος” which means “word”. Neologism is understood as that term that appears in a certain language as new, or also the insertion of a new concept in an entry or word that already exists, or a term that comes from another language in particular. the origin of neologisms is given on several occasions by fashion and thanks to the need for new names.

Neologisms are those entries or new words that in certain cases take time to be officially added to a language; that are created respond to the needs of denomination caused by those changes of a sociocultural nature, by technological and scientific advances or by the desire to expand the expressive possibilities for literary or aesthetic reasons. On the other hand, many of the neologisms that appear may originate from terms that already exist in the same language or from words of another.

According to purism, which is a tendency that rejects lexical and grammatical contributions originating from other languages, there are unnecessary neologisms, such as those that lengthen words thus turning them into archisyllables, but there are also other necessary neologisms, which as an example we can make mention of “seropositive” or “bonobús”. Currently, the pioneers in the propagation or dissemination of neologisms and linguistic loans are the different media. On the other hand, some of these words are characterized by having a brief, fleeting, momentary or passing lapse.
