I will be doing a Conversation with him, with an associated public event. Here is part of his Wikipedia profile:
John Hamilton McWhorter V…is an American academic and linguist who is associate professor of English and comparative literature at Columbia University, where he teaches linguistics, American studies, philosophy, and music history. He is the author of a number of books on language and on race relations, and his writing has appeared in many prominent magazines. His research specializes on how creole languages form, and how language grammars change as the result of sociohistorical phenomena.
So what should I ask him?
And if you wish to register for February 17, here is the link.
