neologismthe

Neologismthe is a coined term used in linguistic discourse to refer to a newly created word (a neologism) and the processes by which it enters and spreads within a language. As a neologism itself, the term is often cited in discussions of word formation and lexical diffusion as a compact label for the lifecycle of new vocabulary.

The name blends "neologism" with the suffix "-the", a playful, pseudo-classical ending employed in some coinages to give a formal or antiquated tone. There is no formal etymology or wide scholarly consensus for the term; references to it are found in niche online forums and speculative glossaries dating to the early 2020s.

In practice, neologismthe is used descriptively to designate a canonical instance of a neologism—the act of coinage, its semantic shift, its rate of adoption, and its incorporation into dictionaries or common usage. For example, the neologismthe "vibe-check" illustrates rapid diffusion from social media into everyday speech.

Because it is informal and unsettled, it has limited acceptance, and many linguists would simply refer to the phenomenon using established terms such as "neologism" or "lexical diffusion."
