A pseudo-anglicism is a word in another language that is formed from English elements and may appear to be English, but that does not exist as an English word with the same meaning. Wikipedia

Word in another language formed using English elements although not existing in English or having a different meaning Wikidata

A word in a language other than English that has an English appearance but is not current in English itself. This may be, for example, because the word was borrowed from a neologism that never entered English common use, or because it was independently derived from an English word, or because it was deliberately coined to resemble English.
