Language and Linguistic Rights

Any drawing of a family member — a parent, grandparent, older sibling, aunt, uncle — in a moment of language sharing. The completion might be: 'They taught me the names of all the foods we eat, songs from when they were young, and how to say I love you in our language. My language is important because it is how my family talks to me, and because when I speak it, I am connected to everyone in my family who has spoken it before.'

Every language is special because each one sees the world in its own way, carries the stories of the people who speak it, and has words and feelings that no other language quite captures. I feel proud of my language when I hear it at home, when I teach a word to a friend, or when someone else recognises it and says something kind.

Losing a language is about more than losing a tool for talking. A language carries the identity of its speakers, the stories of their families, the knowledge built up over generations, and ways of seeing the world that no other language quite captures. When a language dies, a whole way of understanding life dies with it — including important knowledge about local plants, animals, history, and traditions that was never written in any other language. One real example is Hebrew. For nearly 2,000 years, it was not the everyday spoken language of any community. In the late 19th century, a revival movement, led in part by Eliezer Ben-Yehuda, brought it back. Today, over 9 million people speak Hebrew as their daily language. It is the most complete language revival in modern history, and it shows that a dying language can come back when enough people work to save it.

The claim that losing a language is losing a world, not just losing a tool, captures something important about what language actually is. Languages are not interchangeable pieces of equipment that can be swapped without loss. They carry identities, knowledge systems, histories, and ways of seeing that cannot be fully translated. Losing a language is losing something irreplaceable. At the same time, the claim should not be pressed so far that it denies the practical costs of language loss or the difficult choices individual speakers sometimes face. A better position is that language loss is genuinely a loss of a world, while also acknowledging that the value depends on who is doing the judging and that the work of preservation has real difficulties.

The case for the strong claim is substantial. Every language has unique features. Vocabularies reflect what speakers notice and care about — languages spoken by peoples with close relationships to forests, deserts, ice, or oceans often contain rich vocabularies for features of those environments that other languages lack. Grammatical structures shape how speakers think about time, agency, evidence, and relationship. Linguistic research, including the work of Dan Everett on the Pirahã and many others, shows that languages can differ profoundly in the conceptual frameworks they encode. Stories, songs, prayers, and jokes rarely translate cleanly between languages; the original rhythm, resonance, and double meanings are lost.

Furthermore, languages carry knowledge that often exists nowhere else. Indigenous peoples' detailed ecological knowledge — about specific plants, animals, seasons, and environmental patterns — is frequently encoded in their languages in ways that would require extensive documentation to preserve in any other tongue. When a language dies before being fully documented, that knowledge usually dies with it. Medical ethnobotanical research has repeatedly found that Indigenous language speakers know uses for plants that scientific literature had not recorded. This is not sentimentality; it is concrete loss of human knowledge.

Languages also carry identity in ways that make their loss devastating to speakers. Residential school survivors who lost their Indigenous languages describe a wound that affects their whole sense of self. Losing the language of one's mother, one's grandmother, one's community of origin is not equivalent to losing a tool — it is a kind of spiritual injury. The testimonies gathered by truth and reconciliation commissions in Canada, Australia, and elsewhere make this unmistakably clear.

However, the strong claim should not lead us to treat language choices as always wrong when they move toward dominant languages. Individual speakers and families sometimes face real trade-offs. Parents who choose to raise children in a dominant language for economic reasons are not necessarily making a mistake, even if something is lost. Multilingual approaches — preserving mother tongues while adding dominant languages — are often possible but not always. The framework of 'every language must be preserved' can sometimes place heavy demands on individual speakers rather than on the political and economic systems that put their languages at risk in the first place.

There is also genuine philosophical debate about how much of a 'worldview' is carried by language. Strong versions of the Sapir-Whorf hypothesis — the idea that language fundamentally determines thought — are now largely rejected. Weaker versions — that language shapes but does not fully determine perception — are supported. The strong claim about language as a world should acknowledge this scholarly complexity.

The stronger position, then, is that language loss is genuinely a loss of a world in important ways — of identity, knowledge, relational meaning, and ways of seeing — while also recognising the practical pressures that push individual speakers toward dominant languages, and the hard choices communities and families face. Protecting linguistic diversity requires political and economic action at systemic levels, not moralising at individuals trying to survive in systems that have devalued their languages.

In conclusion, the claim captures a truth that purely practical framings of language miss. Language is identity, knowledge, and world. Its loss is real and serious. But honouring this truth well requires addressing the structures that produce language loss, not asking individual speakers to bear all the cost of preservation.

Research since the 1950s has consistently shown that children learn better when early instruction begins in their mother tongue. UNESCO and many education researchers support this approach, called mother-tongue-based multilingual education (MTB-MLE). The evidence shows: children develop literacy more easily in a language they already understand; these literacy skills transfer effectively to second-language learning, making later acquisition of additional languages stronger, not weaker; children who study in their mother tongue for at least 6 years show stronger academic and cognitive outcomes than those taught from day one in an unfamiliar language; drop-out rates are lower among mother-tongue-educated children. Major studies include Ethiopian longitudinal research, Filipino K-12 reforms, and extensive evidence from sub-Saharan Africa.

Despite this, mother-tongue education has not been universally implemented. Several factors explain the gap. Colonial legacies mean many former colonies inherited education systems built in colonial languages — English, French, Portuguese, Spanish — and changing entire systems requires substantial investment in textbooks, teacher training, assessment, and administration. National unity concerns lead some governments to favour a single national language in education, fearing that mother-tongue instruction could weaken national identity. Resource constraints are real: in countries with dozens of languages, providing full mother-tongue education in all is expensive and logistically complex. Political power matters — dominant-language speakers often hold political and economic advantage and may resist changes that would elevate other languages. Parental preferences can also play a role: some parents strongly prefer dominant-language education, believing it will help their children succeed, even where research contradicts this.

Bridging the gap requires sustained political commitment, serious investment, flexibility about which languages receive mother-tongue status at different levels, and willingness to pilot, study, and scale what works. Where this has happened — partially in South Africa, Ethiopia, the Philippines, and elsewhere — implementation is genuinely difficult but the direction is clear. Language choices in education are never purely technical; they reflect histories of power, and changing them requires shifts in those histories.
