On this page you can get a detailed analysis of a word or phrase, produced by the best artificial intelligence technology to date:
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.
For example, English speakers traveling in France may be struck by the "number of anglicisms—or rather words that look English—which are used in a different sense than they have in English, or which do not exist in English (such as rallye-paper, shake-hand, baby-foot, or baby-parc)".
This is different from a false friend, which is a word with a cognate that has a different main meaning. Sometimes pseudo-anglicisms become false friends.
