While Sacagawea could communicate with some Native American tribes, she was not fluent in all the languages encountered during the expedition.
Here's a breakdown:
* Sacagawea: Spoke the Shoshone language and could communicate with other tribes with some variation in her understanding.
* Lewis and Clark: Primarily relied on interpreters hired along the way, who were fluent in the languages of specific tribes they encountered.
So, while Sacagawea was an essential part of the expedition, she was not the main translator. Her ability to communicate with tribes, especially her Shoshone relatives, was invaluable for establishing contact and understanding local customs.
