Echoes in the Silence

“Atamã kawã nawa yurá” [ah-tah-mah kah-wah nah-wah yoo-rah] “My language flows like the river”

This was one of the last songs passed down in Kaixana, fragments of a language preserved by Raimundo Avelino at 78 years old. When he passed away around 2006, these songs that once 200 people sang together disappeared into eternal silence.

Lost Time Along the Japurá River

In Limoeiro village, Japurá municipality, Amazonas state, Brazil, Kaixana echoed for thousands of years. As a branch of the Arawakan language family, it was once spoken by hundreds along the Amazon River basin.

Even in the 1950s, a few speakers remained, but the language rapidly declined due to Portuguese expansion, young people migrating to cities, and the severing of traditional cultural transmission. Kaufman (1994) classified Kaixana in the Western Nawiki Upper Amazonian branch, while Aikhenvald (1999) reclassified it as Middle Rio Negro, North Amazonian. But even then, speakers were already extremely few.

The Solitary Cry of the Last Speaker

According to 2008 records, then 78-year-old Raimundo Avelino was the last person who could speak Kaixana. Living his entire life in Limoeiro, he preserved a language with no one left to converse with. The stories shared with village elders in childhood, lullabies sung by his grandmother, work songs sung with friends – all lived only in his memory.

UNESCO classified Kaixana as “critically endangered,” but it had already reached extinction. Brazil’s Museu do Índio and Museu Goeldi began building digital language archives, but it was too late for complete documentation of Kaixana.

Untranslatable Language of the Soul

“Yakariwá” [yah-kah-ree-wah] – The whispering sound of river water passing through trees. A word expressing the moment when wind, water, and forest meet.

“Tsurihã” [tsoo-ree-hahn] – The first moment when birds awaken in morning mist. Nature’s signal announcing the day’s beginning.

“Nawati” [nah-wah-tee] – The path ancestral spirits take returning along the river. A concept embodying the Amazon worldview of death and life cycling.

Eternal Preservation Through Digital Archives

We cannot resurrect Kaixana. But we can permanently preserve all remaining records and materials digitally. WIA collects scattered linguistic materials, ethnographic records, and voice fragments left by Raimundo to build a permanent digital archive.

Though no one speaks Kaixana as a mother tongue anymore, the Amazonian wisdom, communion with nature, and unique worldview it contained are preserved forever in digital form. Future linguists and Arawakan family researchers will be able to reconstruct the structure and meaning of this lost language through these materials.

The Amazon’s Lost Treasure

What disappeared with Kaixana was not merely a communication tool. A unique classification system for understanding the Japurá riverside ecosystem, distinctive names for hundreds of plant and animal species, traditional knowledge for reading seasonal changes – all vanished together.

This language contained knowledge of Amazonian medicinal plants, fish migration patterns, natural signals predicting wet and dry seasons. The knowledge accumulated by Kaixana people over thousands of years may have held secrets modern science has yet to discover.

After 221 Days, When All Silence Becomes Song

Kaixana’s story is not an end but a beginning. WIA records endangered languages daily for 221 days. As we remember Kaixana today, tomorrow another language’s story will be digitally preserved forever.

The language Raimundo Avelino preserved alone has become humanity’s heritage, remembered by the entire world. His voice has gone silent, but the Amazon’s soul contained in Kaixana will continue echoing in digital eternity.

The Last Song of the Japurá River

“Kawã yurá tsuni waikã”
[kah-wah yoo-rah tsoo-nee wai-kahn]
“My language shall shine as a star”

May this farewell left by Raimundo
Touch the depths of your soul
And echo across time and space forever

With WIA, every voice is eternal
