Gygax on Alignment Languages

I remember reading about Alignment languages as a kid, and thinking they were the dumbest thing ever. We just ignored it.

They’re still kinda dumb, but when I was eight, I clearly skimmed this chapter to get to the interesting stuff (treasure!) and didn’t read the entry very closely—

1e AD&D Dungeon Master's guide, page 24

So alignment languages are more like (unfalsifiable) dog whistles. If you're Chaotic Evil, you're physically unable to replicate the Lawful Good alignment language, even if you turned evil after a lifetime of good deeds.

So that might sound like:
-Have a blessed day!
-Fight on, comrade!
-Love trumps hate!

Except the words catch in your throat and come out as gibberish if you're not of the proper affiliation.

You can’t use your alignment language to make plans in secret. There are no books written in the alignment languages. Gandalf cannot use the Black Speech of Mordor (unless there's something he's not telling us).

That's an interesting game structure, even if the actual implementation launched a thousand angry blog posts.
