"Bona fide" vs "Bonafide" [closed]

Simply put - is it correct to use "Bonafide" instead of "bona fide" (with the space)?

I'm planning to name a product, and wondering if I could use the single word and still be correct.

‘wondering if I could use the single word and still be correct’

No. Bona fide is two words, so ‘the single word’ simply is not ‘correct’.

In branding a product, you may reasonably experiment with any (not-illegal) expression you like. You are free to invent the word ‘bonafide’ if you wish.

It seems to me, however, that compressing bona fide into a single word would be something of a hostage to fortune since the words literally mean ‘in good faith’, and are generally used to indicate reliability.

oxforddictionaries also gives an adverbial definition of ‘Without intention to deceive’.

With that kind of sentiment in mind, it would seem safer to keep the two words as they are. Mangling them could easily be regarded as either willful artifice or blatant ignorance, neither of which would help your marketing.
