Recently on another blog I read a comment offering a few typical observations and almost interesting comparisons of online networks. Then the commenter alerted the post writer to a spelling error with the following admission: "It's actually the reason I'm writing this now."
It's a shame to see a conversation about interesting ideas turns into a prosaic editing session. And the spelling error in this case is actually an interesting example of a reduplicative coda. The spelling of smorgasbord as smorgasborg is relatively common. Below I list the Google™ hit results for "smorgasbord" and several misspellings
The 4th spelling above is even attested in the OED as an erroneous spelling--reasonably related to smørrebrød/smørbrød/smorbrodt: Danish and Norwegian for a type of sandwich.
Does the g occur more commonly or naturally as a coda? Certainly -org would not be more common than -ord -ort -orn or -ork. Tho I'm not going to take the time to count right now. The -g spelling even gets almost 40 times as many hits as the pretty obvious and completely homophonous spelling pun smorgasbored. And if a 'fingerslip' typo is at work here a much more common spelling string like -ore would probably show up more than just 6 times. There's even a January 1964 review in Time Magazine the 1963 film The Prize with the headline/title Smorgasbore (less than enthusiastic).
I'll go so far as to say that it isn't really a typo. I've heard this as a pronunciation as well and this pattern in the orthography looks like a reflection of the pattern in the phonology.
An interesting result: schmorgasborg gets 2,210 hits--more than schmorgasbord which gets 1630; and shmorgasborg (522) gets almost as many as shmorgasbord (682).
Is it contamination by the cybernetic organism⇒ cyborg ⇒ borg compression? Not likely.
The best explanation seems to be an echo in the final syllable.
A bit of a digressive epilogue: The commenter I mentioned tacks the common complaint onto his spiel: "p.s. one of my pet peeves is the misuse of 'your' and 'you're'... how is it that people can't figure out when to use each one???" (peevologist is really so appropriate a term).
People do know how to "figure" it out. People know the rule. They know the difference between the words. But spelling is closely tied to the 'mind's ear' which helps explain why words like to and too are used interchangeably as are there their and they're. I've committed the error many many times. Many. I will commonly interchange where and wear but it's less common for me to confuse them with were. It happens but not as often.
