You will hear people say the C-word. Except, it's a regional language: in British English, c - t has much less of an inflammatory sense than it does in North American English. You can hear someone on British TV called "a c - ting monkey" or a man being called a c - t. The particular fascination of profanity is how culturally specific it is and how it evolves.

Whenever you try and simplify how people speak, it's just hard to squish them into a simple rule. Language doesn't work that way.

Back in the 19th century, our marketing folks decided to play up the refined usage angle because prescriptivism was very popular: our dictionary is where you go to learn anything about anything. That really set the tone in North America for how people responded to dictionaries.

The initial 18th-, 19th-century intention was to give the less-educated lower classes a way to move up into this new, rising middle class, to enable them to fit in. So our view of language as being class-based is an unintended consequence of the drive to help educate rising businessmen.

The history of English is full of that, lots of things done with good intentions that 200 years down the road have resulted in a giant mess, where someone's pet peeves - like John Dryden and his hatred of terminal prepositions - could become real standards.

It's difficult to sit down and write a letter back saying, "you know what, even if we remove the word from the dictionary, people will still continue to use it." That's the tightrope that we walk - "gay marriage" is another example, or the word "nude."

I think when dictionaries define words, there's a sort of hair-splitting that to most people doesn't make any sense, which is we're not describing what a thing is.
