Language is the primary way we communicate with each other, and we have really strong feelings about what words mean, and about good language and bad. Those things are really based on sort of an agglutination of half-remembered rules from high school or college, and our own personal views on language and the things we grew up saying, the things we grew up being told not to say.

What makes autocorrect really interesting for a lexicographer is we read in a very weird way. A lot of times we'll catch things that are so clearly autocorrect typos, and you learn to tell the difference between an honest-to-goodness, ham-fisted typo and an autocorrect typo because the latter will not necessarily be a difference of one letter apart on the keyboard, which is usually what typos are, or it won't be the wrong its or the wrong there.

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.

I make the case in the book that Standard English, that language we all aspire to live and move and have our being within, is actually based on a fiction. It's not anyone's native way of speaking or writing. That's why we have to take classes in it. Language is just really squishy.

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.

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.

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.
