Protologism

Protologism is a term invented by Mikhail Epstein, an American literary theorist, to refer to a new word which has not gained wide acceptance in the language.Protologism describes one stage in the development of neologisms, at which a word is proposed, extremely new, or not established outside a very limited group of people, and coined to fill a gap in the language, with the hope of it becoming an accepted word. The term protologism is autological; it is an example of the thing it describes. Epstein coined the term by combining the Greek words and logos:

I suggest calling such brand new words 'protologisms' (from Greek protos, meaning 'first, original' and Greek logos, meaning 'word'; cf. prototype, protoplasm). The protologism is a freshly minted word not yet widely accepted. It is a verbal prototype, which may eventually be adopted for public service or remain a whim of linguo-poetic imagination.

There is no fixed rule determining when a protologism becomes a stable neologism. According to Epstein, every word in use started out as a protologism, subsequently became a neologism, and then gradually grew to be part of the language.
