Words have always been political, and that means that, in many people's minds, dictionaries are political. Because that's what dictionaries do: they do words.

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.

A lot of people thought oh, we caught the dictionary in racism, or all it takes is a whole bunch of people saying that a word is bad for the dictionary to change it. That's not the case. For nude, things that are called nude color, that color palate has broadened very recently, in the last maybe seven to 10 years, and now covers all skin tones.

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."

It's very easy, when things like the gay marriage write-in happen, to get sick of how people view language and say, "ah, come on it's just a dictionary." But then you hear from people who say if you take out "retarded" it won't exist anymore, and there will be no slurs for people to call my child. And that's just heartrending.

With "marriage," the word gets applied to same-sex marriages by proponents and opponents alike. That means the word itself is changing, and we reflect this change. But because of the idea that the dictionary is the objective voice of authority over culture and knowledge, it reads like approval. It's not a helpful way of looking at lexicography.

There's a measure of prescriptivism and descriptivism in every dictionary. Prescriptivism believes that the language should mirror the best practices of English, and editors are prescriptivist in so far as they don't want to let things they consider to be inelegant or ungrammatical into print.
