Huetar language

Huetar (Güetar) is an extinct Chibchan language of Costa Rica that was spoken by the Huetar people. It served as the lingua franca for precolonial peoples in central Costa Rica, and went extinct in the 17th century. Only a few words in the language are currently known, preserved mainly in the names of various Costa Rican places, such as Aserrí, Barva, Curridabat, Turrialba, Tucurrique, and Ujarrás.

The main source of studies regarding the language is the Costa Rican linguist Miguel Ángel Quesada Pacheco.
