I was just about to praise Household Opera for a major breakthrough in phonetic orthography–Rrrowr!–but then I googled it and came up with 450 hits. Next thing you know, somebody will be writing to tell me it’s actually from Finnegans Wake….
While we’re on the subject, more or less, I have settled on Eeuuww! as my preferred spelling of that now-essential expletive. Any questions?
(I also prefer Fuhgedaboudit, as rendered by Tom Wolfe in The Bonfire of the Vanities, but no standard rendering has yet been universally accepted, alas. These things matter!)
