This study investigates the relationships between four Tupi-Monde languages: Cinta Larga, Suruí, Gavião and Zoró. Two word lists were collected from each of these languages, and they were analyzed using the comparative method. The results show that these languages are not genetically related in the way previously supposed. The possible historical reasons and implications of these new findings are discussed. A new genetic tree is proposed to take into account the new analysis.
