Barbarism

“Barbarism (noun): A word or expression considered ill-conceived usual language standards, such as dubious coinage that is a hybrid of Greek and Latin elements or a crude, ill-adapted neologism, e.g. ‘complected’ (rather than “complexioned”), ‘legalcy,’ or ‘suavitude.’

‘On the other hand, some widely popular examples of sportspeak are barbarism whose use should be a misdemeanor if not a capital offense.’ Red Smith, The New York Times.”
