Most people, if they think at all about the dictionary, think of it as this fixed object given to us from on high. It is the thing that legitimizes language and makes language real. You never think that it's actually compiled by living, breathing nerds like me. When you realize that it's compiled by people, it becomes a different thing, a different kind of document.

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.

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.

We're not saying that marriage, the thing, is now open to anyone of any gender. We are saying, when the word marriage is used in this particular context, this is what it means. And it was the same with "alternative facts." That was a big one. "Feminism" was a big one. And when people came to the "marriage" entry, because we live in the Internet age, they either immediately fire off an email to us saying they're horrified at how commie-pinko-liberal we are, or they fire off an e-mail saying thank you so much for speaking truth to power.

Language is a signifier - it points to something. But those somethings change sometimes. Where the line comes down is that change is not in the dictionary first, it's not: change the signifier and the signified will go away.

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.

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.
