Rooke isn't just learning language, he's learning how to be a person. This supports the idea that language is something that creates relationships and ties people together; it doesn’t exist only on paper. In the same vein, Rooke is also learning how to communicate ideas without using speech, which continues to complicate and expand how the novel defines language. Further, it's important that Rooke isn't the only one learning—Tagaran is too. The exchange of culture and language goes both ways, and though in the larger scheme of things Rooke is part of an oppressive society that is antagonizing and invading Tagaran’s society, as individuals they can (for now) seek to escape the wider environment of colonialism and simply experience each other’s cultures person to person.
