neologism
Noun
(linguistics) A word or phrase which has recently been coined; a new word or phrase.
(linguistics, uncountable) The act or instance of coining, or uttering a new word.

Usage notes
For a word to be no longer considered new, it needs to be understood by a significant portion of the population as having always been a valid word. For that to occur the word must have been in common use for approximately one generation — fifteen to twenty years — but there is no universally accepted measure.
