L'alternance entre créole afro-portugais de Casamance, français et wolof au Sénégal : une contribution trilingue à l'étude du contact de langues

摘要

Casamancese Afro-Portuguese Creole is still largely unknown. The present study is the first description of the language practices of Casamance Creole speakers. The study is based on a first-hand corpus collected during spontaneous discussions among Creole speakers in multilingual cities: Dakar, Thies and Ziguinchor. In this corpus, the main languages in contact are the Casamancese Creole, French and Wolof.This dissertation describes the changes induced by this contact in the corpus, especially the temporal deixis and phenomena specifically affecting noun groups (such as determiners and genitives). The study of these domains has led me to realize that all three languages involved both grammatical and lexical elements are provided by all these languages.Such a scenario is generally not taken into consideration in the theoretical approaches to language contact, which often posit a functional separation of the languages involved based on a dichotomy between matrix language and embedded language, and tend to ignore contact situations involving more than two languages.This dissertation is therefore a contribution to the study of language contact; more specifically, it allows for the possibility to take a fresh look at a trilingual contact situation involving a Creole language and two other languages typologically distant from the former. The inclusion of such a configuration is particularly innovative in the domain of Creole studies, where researchers interested in contact languages focus mainly on situations of contact between Creoles and their respective lexifier languages
