* Czech: The title character, Antonia Shimerda, and her family are Bohemian immigrants, meaning they are originally from Bohemia (now part of the Czech Republic). It's implied that they speak Czech at home, although the narrator Jim Burden doesn't fully understand it.
* German: Other characters, like the saloon owner, are of German descent. There might be instances where German is spoken, but it's not emphasized in the story.
* Native American Languages: Though not explicitly mentioned, the presence of Native American tribes in the area suggests the possibility of indigenous languages being spoken, but again, this isn't a significant aspect of the narrative.
The book primarily focuses on the English spoken by the settlers and the evolving American dialect of the time. The language barrier faced by Antonia and her family is more implied than explicitly shown.
