Re: Reed-Kellogg "really"
I know nothing abour R-K, so my opinions can be safely iignored, but it seems to me that 'really' is inherently different from 'by Jove'. Even if 'really' appears to be used interjectionally, it still has an adverbial force, reinforcing or questioning the truth of the whole statement. It is similar to such adverbs as 'surprisingly'. 'arguably', ' hopefully' or 'actually', which I would not call 'interjections'.
