This thesis analyzes the function of two grammatical forms which bring about the articulation of sentences through adverbial hypotaxis, a mechanism of textual connection characterized by the establishment of semantic-logical relationships, signaling the communicative intentions of the users of the language. These grammatical forms – sem(without) and the conjunctional periphrase semque (unless) - are placed in distinct grammatical classes: preposition and conjunction respectively, due to grammatical conventions. These conventions attribute to the first term, the function of transposing a nominal syntagm into an adnominal or adverbial adjunct within the sentence; and to the second, that of transposing an absolute sentence to a new structure, within which it occupies the position of a constituent, taking up, among other functions, that of the adverbial adjunct, under the form of a sentence. In this perspective, I address the syntactical and semantic re-categorization of the above mentioned preposition, defending the view that it figures as a conjunction not only when it is part of the conjunctional periphrase, but also in in the presence of the verb in the infinitive form, forming reduced infinitive sentences. Using Functional Theory, which analyzes the principles which govern the natural use of language, I discuss the cognitive and interactional motivations which cause the change.With specific reference to the treatment of the process of grammaticalization, I have used the North American branch of Functionalism to explain the fluctuation of category and semantic and discursive fluctuations experienced by this linguistic item. From the observation of data, I have deduced patterns of typical uses of reduced as well as highly evolved sentence structures, emphasizing that these two structures are not always interchangeable. The corpus from which I inventorythe syntactic, semantic and pragmatic properties of the transpositers under investigation, correlating textual and interpersonal functions, is constituted by texts from the argumentative sphere- articles of opinion, editorials and interviews from weekly magazines. I conclude that though the preposition sem does not introduce argumentative terms, it belongs to the listof prepositions which are moderately grammaticalized, and is susceptible to change, exhibiting a diversity of semantic nuances similar to conjunctions.
