At some level language can be represented as a set of elements (words) and a grammar (rules) that describes how to structurally order those elements to generate sentences in that language. A question worth asking is what modes of thought and ideologies are programmed and embedded into us solely by wielding a specific language.
This was observed by Fanon in "Black Skin, White Masks" when he wrote, "I ascribe a basic importance to the phenomenon of language. To speak means to be in a position to use a certain syntax, to grasp the morphology of this or that language, but it means above all to assume a culture, to support the weight of a civilization."
Within the context of colonialism and genocidal practices, we could flip this question and ask what are the effects of linguicide--or the death of a language. What is lost beyond simple words and grammar rules when a language is exterminated? What connections between the people and the environment in which they live are lost with a dead language? On "Thanksgiving" Tiokasin Ghosthorse (Cheyenne River Lakota Sioux) spoke before The National Day of Mourning attendees and addressed this topic. The master's house is decrepit and rapidly approaching full collapse, so attempting to reverse this course using the master's language is insufficient and futile.
What is needed is a new way of thinking which could likely require a new way of communicating. Racism, homophobia, and classism are not native to these shores, and it is rather telling how such concepts are non existent in many if not all native tongues.
