not yet an actual word. incorrectly used when trying to describe something that is the opposite of "genuine." usually confused with "Ingenuous" which means "gullible" and "ingenuity" which means "inventive originality". it is best to use the word "DISINGENUOUS" when you are vying for the antonym of "genuine".

Meaning: adj. Not genuine; false; not authentic. Normally associated with persons, behaviours and experiences rather than items.

Etymology: Contrary to popular belief (google the term for examples), this is in fact a word, and can be cited as far back as the 17th Century:

1675 R. Burthogge Cavsa Dei 352 'A many false, supposititious, and ingenuine' Writings.

Source: Oxford English Dictionary online.

The word can be made by attaching the prefix in- (a variant of un-) to the existing word 'genuine', in parallel to in- + sincere, in- + compatible, in- + valid and so on.

Although it may often be confused with 'ingenuous', this is a simple malapropism and does not affect the validity of the word.
