I’m wondering exactly which grammatical role the word hell takes on in expressions such as
Get the hell out of here
the hell in this case seems to modify the phrasal verb to get out (get out of here quickly may have a similar meaning depending on the context), so I would classify it as an adverb, even though hell itself is a noun. I suspect that the reason for using the hell is that there is no other way of forming an adverb out of hell in an obvious and easily understandable way.
Is the hell simply an adverbial phrase (in addition to being an expletive)? If so, is there a name for creating adverbial phrases from nouns in this way?
(Originally, I was interested in the analogous expression involving f*ck.)
