Craig, a whale biologist in Alaska, wonders how many words have been adopted into English from such languages as Inuit, Yupik, Tlingit and Inupiaq. Indigenous languages in the far North have contributed mukluk, malamute, kayak, and parka. The word parka took an especially long route into English, coming originally from native peoples in the Russian region of the Arctic Circle. Native American terms also give us some familiar animal names, such as opossum and raccoon. This is part of a complete episode.
