Dans cette thèse, j’étudie l’intransitivité scindée dans la famille linguistique arawak (Amérique du sud). L’analyse grammaticale du phénomène de l’intransitivité scindée s’appuie sur la prise en compte d’une part de ses motivations sémantico-pragmatiques, et d’autre part de ses réalisations morphosyntaxiques selon les catégories grammaticales, les changements de diathèse et les facteurs de TAM. En plus des marquages canoniques de l’agent et du patient d’un verbe transitif, les constructions impliquant des marquages non canoniques, comme celles engageant des verbes nominalisés ou un marquage différentiel, ont également été considérées.Cette étude non seulement révèle l’existence d’une grande diversité parmi les sous-types d’intransitivité scindée, mais propose les moyens de comprendre l’évolution diachronique de ces sous-types, avec laquelle ont pu interférer les effets du contact de langues. Les hypothèses avancées sur l’évolution historique des systèmes grammaticaux mettent à jour les voies où plusieurs langues ont pu s’engager vers des alignements à coloration accusative vs. ergative.Au travers de cette orientation, l’étude nous éclaire sur les différentes manières qu’a l’intransitivité scindée d’affecter l’alignement des actants, apportant ainsi sa contribution à la typologie des langues. / In this thesis I study in depth the split intransitivity in the Arawak family of languages of South America. The grammatical analysis of the split intransitivity phenomenon is based on both their semantico-pragmatical motivations and their morphosyntactical realizations according to grammatical categories, valence changes and TAM. Besides, I also take into account constructions involving other types such as nominalized verbs and differential marking.This study not only reveals the existence of a rich diversity of split intransitivity patterns within this family, but it also proposes paths to understand the diachrony of such patterns, involving shifts from ergative alignment to accusative alignment, for which the effects of language contact may have played an important role. In this connection, the study sheds light onto the ways split intransitivity has implication for alignment-type and it is thus of interest for language typology.

Scientific language, in contrast to general language, is characterised by its abstract and implicit style of expression, known as nominal style. A typical feature of this style is the frequent use of nominalizations which tend to be more common in German than in Swedish. This study will investigate whether these differences are also present in highly specialized medical texts. The quantitative and qualitative analysis is based on the translation of two medical articles from Swedish to German. The aim is to find out how often a nominalization in the source text corresponds to a nominalization in the target text, which structural shifts occur and how they influence the degree of nominal style. For this purpose, the concept of the “grammatical metaphor” was applied. The results show that the Swedish source text contains less nominalizations than the German target text. In 30% of the cases, less explicit and more metaphorical information was conveyed in the target text. In most of these cases a Swedish verbal construction was translated into a German nominalization. The metaphorization was often optional and guided by the conventions of medical texts. 65% of the occurrences showed the same degree of grammatical metaphoricity and were thus re-metaphorized. In the remaining 5%, the target text was less explicit and thus de-metaphorized. The Swedish source text proved to be less nominal than the target text.

Dans cette thèse sur la concession en russe moderne, nous avons cerné cette notion en élaborant un schéma prototypique servant à classer différents types de constructions concessives et à intégrer le maximum de structures marquées comme concessives. Ainsi le schéma proposé (p, Cq), basé sur la notion de contraste entre les implications des contenus de p et q, les évaluations de ces contenus ou les actes illocutoires p et q, prend pour principal repère C, conjonction ou préposition concessive. Nous avons étudié la relation concessive dans des constructions bi-Propositives et des propositions simples. Cet ensemble est classé en fonction du statut épistémique de q, puis subdivisé en non-Conditionnel, conditionnel ou contrefactuel. Le deuxième critère de classement est le statut unique ou multiple de q. Dans le premier cas nous avons des constructions non-Généralisantes, dans le second la construction appartient au type généralisant. Nous nous sommes démarquée des recherches traditionnelles en prenant en compte la concession illocutoire : xotja sert à remettre en cause l’énoncé précédent pour une auto-Correction du locuteur qui annonce ainsi le changement du cours de sa pensée. Notre travail nous amène à la conclusion que la concession est un phénomène protéiforme non réductible à une notion de causalité inversée. L’élargissement du champ d’étude permet de jeter un pont entre la notion linguistique et la notion rhétorique de la concession et de donner un tableau plus complet des différentes formes de relation concessive en russe moderne. / In this thesis dedicated to concession in modern Russian we specified the concept by means of a prototypical schema which we applied to classify different types of concessive constructions. This schema aims at embracing the majority of sentences marked as concessive. The main mark of the proposed schema (p, C q), based on the idea of contrast between the implications of p and q contents, assessments of these contents or p and q speech acts, is the connective C, a concessive conjunction or preposition. We studied concessive relations in both complex sentences and simple sentences. They are classified according to the epistemic status of q and subdivided into non-Conditional, conditional and counterfactual. The second criterion of classification is the single or multiple status of q. According to it we have, on the one hand, non-Generalized concessive constructions and, on the other, generalized concessive constructions. Outstepping the traditional research, we made a point of studying illocutionary concession as part of the whole. Indeed, xotja in discourse is used by the speaker as a self-Correction technique in order to reject the previous utterance pointing thus the deviation of their thought. As a result of our research we come to the conclusion that concession has multiple forms and cannot be reduced to inoperant causality. Due to a wider research scope we managed to bridge the linguistic and rhetoric concessions and to give a broader view of different forms of concessive relations in modern Russian.
