Cette thèse porte sur la grammaire de la langue namtrik, connue aussi comme namui wam ou guambiano, appartenant à la famille linguistique Barbacoa (Curnow & Liddicoat, 1998). Cette langue est parlée dans le sud-ouest de la Colombie sur la cordillère des Andes par environ 23.242 (Moseley, 2019) locuteurs dans des communautés du département du Cauca. Cette thèse est une description d’une variété très menacée du namtrik parlé dans la communauté de Totoró par 1% de la population de la communauté (environ 76 personnes). Cette dissertation, menée sous la direction d’Antoine Guillaume (DDL, CNRS & Université lyon 2) et le co-encadrement de Tulio Rojas Curieux (Université du Cauca & GELPS), constitue la première grammaire descriptive de la langue namtrik dans un cadre typologique moderne. / This dissertation is a comprehensive grammatical description of Namtrik, also known as Guambiano, an under described language of the Southwestern Colombian Andes spoken by about 23.242 people (Moseley, 2019). This grammar focus in a highly endangered dialect of Namtrik, spoken in the community of Totoró by 76 native speakers (1% of a total population of 7023 people) who are all over 50 years (Gonzales 2013:11). This dissertation is co-supervised by Antoine Guillaume (DDL, CNRS & Université lyon 2) and Tulio Rojas Curieux (Université du Cauca & GELPS). This dissertation includes a phonological, morpho-phonological, morphological and syntactic description of this language and is based on a Namtrik audio-video corpus collected in collaboration with trained members of the community. The HRELP-SOAS program funded this doctoral research project and also a documentation project of the language. / Esta tesis doctoral dirigida por Antoine Guillaume (DDL, CNRS & Université lyon 2) y Tulio Rojas Curieux (Universidad del Cauca), presenta una descripción de la gramática de la lengua namtrik, también conocida como namui wam o guambiano, perteneciente a la familia barbacoa (Curnow y Liddicoat 1998). Esta lengua es hablada en el suroccidente colombiano por alrededor de 23.242 personas (Moseley, 2019), sobre la cordillera de los Andes, en el departamento del Cauca, en los resguardos de Guambia, Ambaló, Totoró, Quisgó y Jambaló. Esta gramática describe una variante seriamente amenazada delnamtrik, hablada en el resguardo de Totoró por alrededor de 76 hablantes, que corresponden al 1% de la población total de la comunidad (7023 habitantes) (Gonzales 2013).

Egophoric marking as a potentially categorical expression in language is conceived of as a binary semantic contrast that marks an event as either involving one of the speech act participants (egophoric), or as one that does not (non-egophoric). Prima facie, the egophoric marking pattern resembles person indexing and has been interpreted as such. However, it appears that what is marked does not simply correspond to indexing the speech act roles of speaker and addressee. Rather, egophoric marking appears to encode the speech participant’s respective access to events/information in terms of ‘involvement’ and is therefore more akin to epistemic categories, such as evidentiality. This thesis presents a comparative study of egophoric marking on the basis of data from descriptions of relevant languages from the Barbacoan (South America), Nakh-Daghestanian (Caucasus) and Tibeto-Burman (Himalaya) language families. The study covers grammatical and functional properties, as well as diachronic aspects of egophoric marking systems. The findings are discussed in relation to typological studies on person and evidentiality in order to determine similarities and differences between egophoric marking and these associated categories. / Egoforicitet som en potentiell språklig kategori innebär en semantisk kontrast mellan händelser som involverar någon av taldeltagarna (egoforisk), och händelser som inte gör det (icke-egoforisk). Vid första anblick kan egoforicitet verka snarlik personkongruens (personböjning), och egoforicitet har ibland analyserats som sådan. Vid närmare undersökning uttrycker egoforicitet deltagarnas tillgång till en händelse med hänsyn till deras respektive delaktighet i denna, snarare än deras roller som talare eller mottagare. Detta gör att egoforicitet är mer lik en epistemisk kategori som t.ex. evidentialitet än personböjning. Uppsatsen diskuterar grammatiska, funktionella och diakrona egenskaper hos egoforicitets- markeringssystem. En typologisk-jämförande studie av egoforicitet görs baserad på data från beskrivningar av relevanta språk ur de Barbakoanska (Sydamerika), Nakh-Dagestanska (Kaukasus), och Tibetoburmesiska (Himalaya) språkfamiljerna. Resultaten jämförs med typologiska studier av personböjning och evidentialitet med syfte att identifiera likheter och skillnader mellan egoforicitet och dessa närbesläktade kategorier.
