What the heck is Proto-Indo-European?

In this episode, I explore a partially reconstructed language known as Proto-Indo-European, a language believed to be the origin of most Indo-European languages. Along the way, I visit some feats and foibles of early European archaeology, describe the rediscovery of an ancient language and civilization, and share the main pet peeve of most linguists. All wrapped up with my usual sense of humor and love for language and history.
