Neologism
newly coined word, phrase or meaning / From Wikipedia, the free encyclopedia
Neologism is a word that is new (15 to 20 years or less) but older and used more than a protologism.[1][2][3] Neologisms are often directly attributable to a specific person, publication, period, or event. Νεολεξία (Greek: a "new word", or the act of creating a new word) is a synonym for it. The term neologism was first used in English in 1772, borrowed from French néologisme (1734).[4]
Using an existing word or phrase in a new context is also called neologism.[5][6] The process of using a word in such a new context is sometimes called a semantic extension.[7][8] A new word that has not been used by anyone but the inventer is a protologism.[9][10][11]
