Several of Costa Rica’s Indigenous languages are at risk of disappearing as the number of fluent speakers declines and younger generations increasingly grow up speaking Spanish. Cabécar and Bribri remain the country’s most widely spoken Indigenous languages, with more than 8,000 speakers each, according to estimates cited by researchers. Researchers have warned that the loss of an Indigenous language reaches far beyond vocabulary. Bribri and Cabécar need stronger transmission to new generations, while Boruca and Brörán require more intensive recovery efforts based on surviving records and community knowledge. The future of these languages will ultimately depend on whether younger Indigenous Costa Ricans have meaningful opportunities to learn, speak and value them in daily life.
