Neologism

from Greek νέο- néo-, "new" and λόγος lógos, "speech, utterance") is a relatively recent 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.[1]
 However irritating neologisms can be, they are sometimes near-compulsory. When a compact, comparatively simple thought is forced to route itself, repeatedly, through crudely-stitched terminological tangles, the missing adequate word fosters the linguistic equivalent of a nagging hunger. Word invention becomes a simple prerequisite of smooth cognitive function. [Nick Land, July 29, 2013]List of neologisms by Nick Land: Urbanomy, Templexity, ...
