Morphology

fuck + know

The phrase uses the expletive 'fuck' as an emphatic/placeholder with 'knows' to convey 'nobody/I have no idea', which is not a literal composition of the two words. A B1 learner who knows 'know' and recognises 'fuck' as a vulgar intensifier might infer it functions like 'who the hell knows' and guess the general sense, but the usage is idiomatic and register-specific, so it is only partially predictable.

Etymology

Fuck knows is a very rude, informal way to say you do not know something. It likely comes from older sayings like 'God knows' or 'who knows', but with the strong word fuck added to knows to make it more shocking and forceful, so it now means 'I really have no idea'.
