A'ingae (or Cofán, ISO 639-3: con) is an Amazonian isolate spoken by ca. 1,500 Cofán people in the province of Sucumbíos (northeast Ecuador) and the department of Putumayo (southern Colombia). In addition to documenting and describing the language, I have explored a number of theoretical topics, including the morphophonology of stress and glottalization, recent sound changes, negative agreement on nominalizing heads, apprehensional semantics, second-position clitics, pied-piping, conditional constructions, and other.

1.1.1  ... at the interface with complementizer morphosyntax
I show that the patterns of stress and glottalization in subordinate clauses are sensitive to the morphological structure of the subordinate verb, violating bracket erasure (Kiparsky, 1982). I capture the pattern with phase faithfulness constraints (McPherson and Heath, 2016) indexed to the category of the input phase.

1.1.2  ... at the interface with verbal morphosyntax
I describe the rich verbal morphology of A'ingae and analyze the language's phonology of stress and glottalization. I argue that morpheme-specific stress deletion cannot be captured representationally. I demonstrate that the tier of the A'ingae glottal stop differs between two morphological domains and interacts with stress deletion, bearing out a new prediction of Cophonologies by Phase (Sande, Jenks, and Inkelas, 2020).

1.1.3  ... in reduplication
I describe and analyze the A'ingae superplural reduplicative suffix -ʔσ, which requires that the base and the reduplicant form (ˈσ1̆σ2ʔ)σ2. I model this behavior with a reduplicant-specific cophonology (e.g. Orgun, 1996), which consists of a ranking of constraints motivated elsewhere in the language's grammar (Dąbkowski, t.a.). Thus, I demonstrate that A'ingae reduplication is highly phonologically optimizing.

I document a typologically unusual process of postlabial raising in A'ingae. I present a model which derives the postlabial raising through an interaction of constraint weights and the number of Q-Theoretic (Inkelas and Shih, 2016, 2017) subsegments, contributing a novel argument for the representations of Q-Theory. I argue that the contemporary variation in the distribution of ai and ɨi is a consequence of sound change, followed by recent replacement and partial paradigmatic leveling.

I identify the "nominal negative" suffix -a nn, which obligatorily attaches to noun phrase-internal functional heads that nominalize negated predicates. I propose that -a nn expones agreement with the Neg(ative) feature on T. Therefore, I document the first case of agreement with polarity on nominalizers to date.

In a collaborative project with Scott AnderBois, we describe and analyze different uses of the A'ingae apprehensional morpheme -sa'ne appr. We put forth a formal account of rationale and precautioning clauses, which captures language-internal asymmetries and typological trends within this semantic domain. We propose a typological framework for describing and comparing apprehensional synchrony and diachrony.

I argue that A'ingae second-position clitics are matrix clausal C-heads. Thus, I show that—despite its apparent non-configurationality—A'ingae has a structured left periphery. I describe A'ingae pied-piping structures and provide a Q-based (Cable, 2010) analysis thereof.

I have documented A'ingae in the indigenous communities of Dureno and Sinangoé (Sucumbíos, Ecuador) and remotely. I have deposited over 14h of oral narrative video recordings (of which 2h30min transcribed and translated) and elicitation data, including fieldnotes and over 70h of audio recordings. I have played a key role in developing a FLEx database of morphologically analyzed A'ingae texts.
