"Chamber's is wrong, of course. They just haven't got the balls to stand up to misspellers. They just record.:-)"

No... Chambers is RIGHT. Just as fo'c's'le is accurate for forecastle, focussed is accurate for folk cussed, only he left the "'" out as it should read "fo'cussed".   That's cussed hard to explain to you folks and folkies and I also must admit that the grammatical construction is awkward to say the least but, Uh, what were we talking about?

Peace, Bob! We surrender! Keep your garlic and anchovy breath at home....PUH-LEEEZE!
