In many Indigenous languages of the Americas, demonstratives are said to encode whether the referent is visible. Some scholars, however, argue that all visibility meanings in demonstratives are epiphenomenal on spatial, epistemic modal, or nonvision evidential content. Drawing on elicitation, experimental data, and corpus data collected in fieldwork, I argue that two demonstratives of Ticuna (isolate; Brazil, Colombia, Peru) do display visibility meanings. These meanings are encoded and concern the SENSE OF VISION—not space, epistemic modality, or nonvisual forms of evidentiality. These findings support a view of demonstrative meaning as grounded in the perceptual capacities of the human body.
This article is dedicated to the memory of Ling Cándido Serra, a Ticuna educator, author, and language activist. One of my first Ticuna teachers, Cándido Serra died of COVID-19 in May 2020. He was only forty-five.
I thank all of the Ticuna speakers who have participated in my research, especially those who contributed data discussed here: Angel Bitancourt Serra, Yaneth Cándido Guerrero, Elvira Coello Guerrero, Marcelo Farías Cayetano, Adriana Farías Gómez, Menris Farías Gómez, Deoclesio Guerrero Gómez, Diandra Rimabaque Witancort, Katia Lucero Salate Cándido, Lilia Witancort Guerrero, Sótil Suárez González, ‘ECP’, and the families in examples 1 and 2. I am especially grateful to Angel Bitancourt Serra for his work transcribing the conversational corpus.
