A neologism (/niːˈɒlədʒɪzəm/; from Greek νέο- néo-, "new" and λόγος lógos, "speech, utterance") is the name for a relatively new or isolated term, word, or phrase that may be in the process of entering common use, but that has not yet been fully accepted into mainstream language. Neologisms are often directly attributable to a specific person, publication, period, or event.
