Children all over the world learn language, yet the contexts in which they do so vary substantially. This variation needs to be systematically quantified to build robust and generalizable theories of language acquisition. We compared communicative interactions between parents and their 2-year-old children (N = 99 families) during mealtime across…

The Portuguese policies of colonisation and Christianisation were closely linked. In 1549, the Portuguese monarchy adopted Catholicism as the official religion of the colonial administration and requested that the Society of Jesus establish the Catholic faith among the indigenous people in Brazil. The Jesuits established catechesis, founded the…

Linguistic and anthropological research has demonstrated that language ideologies play a complex role in contexts of language endangerment, as well as in revitalization initiatives. In this paper, we articulate some central ways in which these beliefs and interests can translate into significant barriers to successful language revitalization.…

This paper uses the themes of language rights, language choice, and language risk to consider linguistic insecurity in the Northwest Amazon (Upper Negro river) region of Brazil. Because the region is home to a large number of languages (c. two dozen), the idea of preserving this diversity is a popular theme in discourses about language in the…

The "Apinayé" are a Brazilian indigenous ethnic group that live in a transition zone between the "Cerrado" and the Amazon. This study primarily aims to understand the meaning that art holds for "Apinayé" indigenous students at a Brazilian Indigenous School. We used an ethnographic research methodology, while also…

This article looks at what origin stories teach about the world and what kind of material presence they have in Southwestern Amazonia. We examine the ways the Apurinã relate to certain nonhuman entities through their origin story, and our theoretical approach is language materiality, as we are interested in material means of mediating traditional…

Ticuna (ISO: tca) is a language isolate spoken in the northwestern Amazon Basin (Brazil, Colombia, Peru). Ticuna has more speakers than almost all other Indigenous Amazonian languages and -- unlike most languages of the area -- is still learned by children. Yet academic linguists have given it relatively little research attention. Therefore, to…

This paper examines the implications and implementation of official language policy designed to support endangered Indigenous languages in the municipality of São Gabriel da Cachoeira, Amazonas, Brazil. The policy, in place since late 2001, declared three of the region's many Indigenous languages (Nheengatú, Tukano, and Baniwa) to be…

The aim of this chapter is to take a critical and decolonial stance towards the experiences of Indigenous people in the urban diasporas of Brazil. We do this by discussing ethnographic data that provide insights into the impact of this migration on the construction of the identities of Indigenous Brazilians who move to urban spaces and consider…

This paper presents findings from an extensive study conducted in Brazil. The main subjects of the study were Bulgarian children living and studying in Brazilian schools. The main goal was to indicate what kind of problems and obstacles they experience during the school time in Brazil and how the Brazilian government and people support these…

This dissertation explores the way Kotiria/Wanano (E. Tukanoan, Kotiria hereafter) women of the Brazilian "Alto Rio Negro" (ARN) contrive (McDowell 1990) "kaya basa" "sad songs" using linguistic and musical resources to construct songs that express loneliness and other private emotions, while also creating alliances…

In studying language policy, it is not enough to look at central government management, but also at the influence of managers at levels ranging from the family to international organizations. Actual cases reveal that there are also non-linguistic forces such as demography, war, civil strife, and economic breakdowns which have major effects. This…

In the last decades, the documentation of endangered languages has advanced greatly in the Americas. In this paper we survey the role that international funding programs have played in advancing documentation in this part of the world, with a particular focus on the growth of documentation in Brazil, and we examine some of the major opportunities…

This paper describes the methods used to study the tone and some related phenomena of the language of the Gavião of Rondônia, Brazil, which is part of the Mondé branch of the Tupi family. Whistling of words by indigenous informants was discovered to be a very effective method for obtaining phonetic accuracy in tone and length. Methods were devised…

Linguistic relativity, the idea that language affects the way that people think, and that people who speak different languages think differently, has implications for mathematics education because people use different languages to teach, learn and practice mathematics. This paper reviews research on linguistic relativity and number, looking at…
