Minerva teaches the “Homesteaders” a few words of “the language”. What is the significance of Minerva teaching the group “language”?

Frenchie sees Minerva as a burden, he doesn't appreciate her for what she brings to the group... culture and history. Ironically, he has just sympathized with Rose for having to stay behind and take care of Minerva... not knowing that Minerva was actually sharing something he desired to learn.
