Romani has a system of synthetic valency-changing morphology to systematically increase or decrease the valency of verbs. Historically, valency-changing suffixes were used to change the valency structure of verbs, to derive new verbaF stems from nonverbal roots, and to integrate loan verbs into the language according to their valency structure. Present-day Romani dialects differ with respect to productivity and functions of the individual morphemes, as well as with respect to the overall productivity of verb derivation by means of synthetic morphology. This dissertation investigates different aspects of the multi-functionality of Romani transitive suffixes in present-day Romani dialects.

Le romani, ou romanes, est une langue parlée historiquement par des communautés qui s’autodénomment « Roms », « Sintos » et « Calos ». Dans cette thèse, on se propose d'analyser une page du réseau social Facebook, comportant de nombreux messages en langue romani. Dans un premier temps, nous identifierons les dialectes présents sur la page et étudierons la diversité des pratiques orthographiques. Puis, on analysera comment la variation est prise en compte par les locuteurs, en évoquant les problématiques d'intercompréhension, d'identité et de revitalisation. Le but de notre recherche est de faire un état des lieux des besoins, réussites et représentations des locuteurs du romani afin d’accompagner ce qui pourrait être un processus d’autogestion langagière. / Romani, also known as Romanes, is a language historically spoken by communities who call themselves “Roma”, “Sinti” and “Kalo”. The purpose of this thesis is to study a page of the social network Facebook which includes many messages written in Romani language. First of all, we will identify the dialects used on the page and we will describe the diversity of spelling practices. Then, we wil analyze the way variation is taken into account by the speakers, discussing the issues of mutual understanding, identity and revitalization. Our research focuses on determining the needs, successes and representations of the Romani speakers in order to support a possible linguistic self-management.
