Este trabalho trata sobre os verbos inacusativos e a livre inversão do sujeito em sentenças declarativas do português brasileiro (PB). É um estudo, com base em revisão bibliográfica, à luz da Sintaxe Gerativa, sob a perspectiva da Teoria da Regência e da Ligação (TRL), proposta por Chomsky (1981), em conformidade com o modelo Princípios e Parâmetros. Primeiramente, é feito um apanhado de tópicos fundamentais (Léxico, Subcategorização Verbal, Teoria do Caso, Teoria Theta, Estrutura de Argumentos) para a TRL, bem como relacionados ao assunto a ser discutido. Após essa exposição, são apresentados os verbos inacusativos (monoargumentais) e as suas especificidades. É feita uma comparação entre os verbos inacusativos e os inergativos, tendo em vista serem ambos monoargumentais. Apesar disso, apresentam estruturas sintáticas completamente distintas. Suas estruturas-D mostram tais diferenças. Os inacusativos subcategorizam um Determiner Phrase (DP) complemento (posição de objeto). Os inergativos selecionam somente argumento externo. Quando ocorre a inversão do DP sujeito, este permanece em sua posição de base, dentro do V(erb)P(hrase). De acordo com autores relevantes (Pontes, 1986; Kato, 2000; Menuzzi, 2003) para este trabalho, os verbos inacusativos são compatíveis com a ordem V(erbo)S(ujeito) no PB. Nas sentenças VS com inacusativos, são verificadas duas possibilidades de concordância. Quando o verbo concorda com o DP sujeito pós-verbal ([pro] Chegaram as visitas), a concordância resulta da cadeia entre o DP sujeito pós-verbal e o expletivo nulo pro pré-verbal. Quando o verbo permanece na 3ª pessoa do singular ([pro] Chegou as visitas), a concordância é realizada com o expletivo nulo pro pré-verbal, que, de acordo com Mioto et al. (2007), é singular. A concordância com o expletivo pré-verbal é como no francês, por exemplo. Porém, no francês, o expletivo pré-verbal não é nulo, é lexical (Il). / This academic work deals with the unaccusative verbs and the free inversion of the subject in declarative sentences in Brazilian Portuguese (BP). This study is based on a bibliographic review, in the light of the Generative Syntax, under the Government-Binding (GB) Theory. It is proposed by Chomsky (1981), in accordance with the Principles and Parameters model. Firstly, a summary of the fundamental topics (Lexicon, Verb Subcategorization, Case Theory, θ-Theory, Argument Structure) within the GB is made, not to mention that these topics are absolutely related to the main subject. Thereafter, the unaccusative verbs (monoargumental) and their particularity are presented. A comparison is made between the unaccusative and the inergative verbs. Although they are both monoargumental verbs, they have different syntactic structures from each other. Their Dstructures show such differences. The unaccusative verbs subcategorize a Determiner Phrase (DP) complement (in the object place), while the inergative ones select an external argument. When the inversion of the DP subject occurs, it remains in its original position within the Verb Phrase (VP). According to relevant authors (Pontes, 1986; Kato, 2000; Menuzzi, 2003) to this work, the unaccusative verbs are compatible with the V(erb)S(ubject) order in BP. The occurance of two kinds of agreement is verified in the sentences when the DP subject occupies the post-verbal position. When the verb agrees with the post-verbal DP subject ([pro] Chegaram as visitas), the agreement results from a chain between the post-verbal DP subject and the null expletive pro. When the verb remains in the 3rd person of singular ([pro] Chegou as visitas), it reveals that the agreement is with the pre-verbal null expletive pro, singular according to Mioto et al. (2007). The agreement with the pre-verbal expletive is likewise in French. However in French the pre-verbal expletive is not null; it is the lexical one il.

Este trabalho trata do uso dos verbos modais em manuais de aviação em inglês sob uma perspectiva da lingüística de corpus. O objetivo é gerar subsídios que permitam elaborar materiais didáticos que reflitam as estruturas lingüísticas como aparecem em seu contexto de uso. Parte-se da hipótese de que o uso dos verbos modais no corpus de estudo apresenta peculiaridades com relação à freqüência de ocorrência, estrutura sintática e sentidos. O corpus de estudo é composto de três manuais técnicos da aeronave BOEING 737, sendo dois manuais de operações destinados a pilotos e um manual de manutenção destinado a mecânicos. A pesquisa é realizada em três etapas. Na primeira etapa é realizado um contraste entre o corpus de estudo, um corpus de referência de inglês geral e um corpus de contraste composto de manuais de sistemas operacionais para computadores pessoais. Esse contraste visa a verificar as diferenças de ocorrências entre os verbos modais e as suas estruturas sintáticas. Depois, são realizadas comparações entre os três manuais que compõem o corpus de estudo também com relação às freqüências dos modais e suas estruturas sintáticas. Na terceira etapa são verificadas as colocações principais de cada VM no manual de manutenção e em um dos manuais de operações. Outro objetivo desta investigação é contrastar o manual de manutenção e um livro didático que tem por objetivo ensinar inglês técnico para mecânicos de aeronaves. Nesse sentido, é feita uma análise do livro no que tange os verbos modais e sugeridas algumas modificações. O trabalho reúne referenciais teóricos da Lingüística de Corpus, Lingüística das Linguagens Especializadas e Verbos Modais. Os resultados do trabalho mostram que há diferenças entre a presença dos modais nos três corpora pesquisados e principalmente entre os três manuais que compõe o corpus de estudo. O estudo mostra a importância de realizar pesquisas baseadas em corpus para revelar as peculiaridades de uma linguagem especializada e assim fornecer subsídios para a elaboração de material didático com propósitos específicos mais de acordo com as necessidades do público alvo. / This thesis is about the use of modal verbs in aviation manuals in the light of corpus linguistics. The goal is to gather subsides to enable the creation of classroom material which presents the linguistic structures as they appear in their natural context. The hypothesis is that the use of modal verbs in the corpus has peculiarities in terms of frequency, syntactic patterns, and meanings. The aviation corpus is composed of three manuals from the BOEING 737 aircraft: two operations manuals directed to pilots and one maintenance manual directed to mechanics. The research has been carried out in three stages. In the first stage, the aviation corpus is contrasted to a reference corpus and another specialized corpus composed of personal computer operational systems. Such contrast aims at verifying the differences in the number of modal tokens and their syntactic patterns. In the second stage, the three manuals that make up the aviation corpus are compared in terms of modal frequencies and their syntactic patterns. In the third stage, the main collocations of each modal are checked. This thesis also aims at contrasting the maintenance manual and a course book designed to teach aviation English to mechanics. Thus, an analysis of the modal verbs in the course book is carried out and changes to the book are suggested. This thesis brings together theoretical assumptions from Corpus Linguistics, the Linguistics of Specialized languages and Modal Verbs. The results point out that there are differences in the use of modal verbs in the three investigated corpora and mainly among the three manuals that compose the aviation corpus. This study shows the importance of corpus based research to reveal the peculiarities of a specialized language and, therefore, provide input to produce specific pedagogical material which better meets the needs of the target public.

Le traitement automatique de la langue quechua (TALQ) ne dispose pas actuellement d'un dictionnaire électronique des verbes, du français-quechua. Pourtant, un projet visant la traduction automatique nécessite au préalable, entre autres, cette importante ressource.Cette thèse consiste à élaborer un dictionnaire électronique français-quechua des verbes. La réalisation d'un tel dictionnaire peut ouvrir également de nouvelles perspectives dans l'enseignement à distance, dans les domaines de l'accès multilingue aux informations, l'annotation/l'indexation des documents, la correction orthographique et pour le TAL en général. La première difficulté consiste à sélectionner un dictionnaire français comme base de travail. Parmi les nombreux dictionnaires français, il en existe très peu en format électronique, et moins encore ceux dont les sources soient en libre accès au public. Parmi ces derniers, l'ouvrage Les verbes français (LVF), contenant 25 610 sens verbaux, que Jean Dubois et Françoise Dubois-Charlier ont publié chez Larousse en 1997, est un dictionnaire particulièrement complet ; de plus il a l 'avantage d'avoir une licence « open source » et un format compatible avec la plateforme NooJ. En tenant en compte ces considérations nous avons choisi traduire ce dictionnaire en quechua.Cependant, cette tâche se heurte à un obstacle considérable : le lexique quechua de verbes simples compte moins de l 500 entrées. Comment faire correspondre 25 610 sens verbaux français avec seulement 1 500 verbes quechua ?Sommes-nous condamnés à utiliser beaucoup de polysémies? Par exemple, dans LVF il y a 27 sens verbaux du verbe « tourner » ; doit-on tous les traduire par muyuy ? Ou bien, pouvons-nous utiliser une stratégie particulière et remarquable de la langue pour répondre à ce défi : la génération de nouveaux verbes par dérivation suffixale ?Nous avons inventorié tous les suffixes du quechua qui permettent d'obtenir une forme dérivée possédant le comportement d'un verbe simple. Cet ensemble de suffixes que nous appelons SIP_DRV, contient 27 éléments. Ainsi chaque verbe quechua transitif ou intransitif donne naissance à au moins 27 verbes dérivés. Il reste cependant à formaliser les paradigmes et grammaires qui vont nous permettre d'obtenir les dérivations compatibles avec la morphosyntaxe de la langue. Cela a été réalisé avec NooJ.L'application de ces grammaires nous a permis d'obtenir 40 500 unités linguistiques conjugables (ULAV) à partir de 1 500 verbes simples quechua. Ce résultat encourageant nous permet d'envisager une solution favorable à notre projet de traduction des 25 000 sens verbaux du français en quechua.À ce stade, une nouvelle difficulté apparaît : la traduction en français de cette quantité énorme des formes verbales conjugables générées, dont sa résolution est essentielle pour notre projet de traduire une partie importante des vingt-cinq mille verbes français en quechua.Afin d'obtenir la traduction de ces ULAV, nous avons besoin d'abord de connaître la modalité d'énonciation qu'apporte chaque SIP quand il s'agglutine au radical verbal pour le transformer. Chaque suffixe peut avoir plusieurs modalités d'énonciation. Nous les avons obtenus à partir du corpus, de notre propre expérience et quelques enregistrements dans le terrain. Nous avons ainsi construit un tableau indexé contenant toutes ces modalités. Ensuite, nous utilisons des opérateurs de NooJ pour programmer les grammaires qui présentent la traduction automatique en une forme glosés de modalités d'énonciation.Finalement, nous avons développé un algorithme qui nous a permis d'obtenir la traduction réciproque du français vers le quechua de plus de 8 500 sens verbaux de niveau 3 et un certain nombre de sens verbaux de niveau 4 et 5. / The automatic processing of the Quechua language (APQL) lacks an electronic dictionary of French­ Quechua verbs. However, any NLP project requires this important linguistic resource.The present thesis proposes such a dictionary. The realization of such a resource couId also open new perspectives on different domains such as multilingual access to information, distance learning,inthe areas of annotation /indexing of documents, spelling correction and eventually in machine translation.The first challenge was the choice of the French dictionary which would be used as our basic reference. Among the numerous French dictionaries, there are very few which are presented in an electronic format, and even less that may be used as an open source. Among the latter, we found the dictionary Les verbes français (LVF}, of Jean Dubois and Françoise Dubois-Charlier, edited by Larousse en 1997. lt is a remarkably complete dictionary. lt contains 25 610 verbal senses and with open source license. lt is entirely compatible with the Nooj platform. That's why we have chosen this dictionary to be the one to translate into Quechua.However, this task faces a considerable obstacle: the Quechua lexicon of simple verbs contains around 1,500 entries. How to match 25,610 French verbal senses with only 1,500 Quechua verbs?Are we condemned to produce many polysemies? For example, in LVF, we have 27 verbal senses of the verb "tourner" to turn; should we translate them all by the Quechua verb muyuy to turn? Or, can we make use of a particular and remarkable Quechua strategy that may allow us to face thischallenge: the generation of new verbs by suffix derivation?As a first step, we have inventoried ail the Quechua suffixes that make possible to obtain a derived verbal form which behaves as if it was a simple verb. This set of suffixes, which we call IPS_DRV, contains 27 elements. Thus each Quechua verb, transitive or intransitive, gives rise to at least 27 derived verbs. Next, we need to formalize the paradigms and grammars that will allow us to obtain derivations compatible with the morphology of the language. This was done with the help of the NooJ platform.The application of these grammars allowed us to obtain 40,500 conjugable atomic linguistic units (CALU) out of 1,500 simple Quechua verbs. This encouraging first result allows us to hope to get a favorable solution to our project of translation of the 25,000 verbal senses of French into Quechua.At this point, a new difficulty appears: the translation into French of this enormous quantity of generated conjugable verbal forms. This work is essential if we want to obtain the translation of a large part of the twenty-five thousand French verbs into Quechua. ln order to obtain the translation of these CALUs, we first needed to know the modalities of enunciation that each IPS have and transmits to the verbal radical when it is agglutinated to it. Each suffix can have several modalities of enunciation. We have obtained an inventory of them from the corpus, our own experience and some recordings obtained in fieldwork. We constructed an indexed table containing all of these modalities.Next, we used NooJ operators to program grammars that present automatic translation into a glossed form of enunciation modalities.Finally, we developed an algorithm that allowed us to obtain the reciprocal translation from French to Quechua of more than 8,500 Verbal senses of Level 3 and a number of verbal senses of Levels 4 and 5.

Text in Afrikaans / Twee sentrale probleme word hier ondersoek, naamlik die daarstelling van 'n teoreties adekwate model om leksikale valensie te verreken en die problematiek rondom die beskrywing van Afrikaanse bewegingswerkwoorde. Die vertrekpunt is dat 'n teorie van UG lesikale valensie slegs ten dele verreken. So 'n teorie is gemoeid met die vorm van 'n konstruksie wat op LF-vlak leesbaar is. Gevolglik beskryf 'n teorie van UG valensie net in universele sintakties-kategoriale terme. In hierdie studie word die semantiese en pragmatiese komponente van 'n valensieteorie derhalwe uitgebou sodat daar 'n duideliker begrip verkry kan word van die wisselwerking tussen alle veranderlikes van valensie op 'n taalspesifieke LF-vlak. 'n Valensieteorie word op eklektiese wyse saamgestel uit verskeie ander teoriee. Die apparaat om die sintaktiese komponent van 'n valensieteorie te beskryf, word aan TGGmodelle ontleen. Die semantiese komponent van die teorie word aangevul vanuit die Konseptuele Semantiek en die pragmatiese komponent daarvan vanui t kogni ti ewe grammatikamodelle. Die interaksie tussen hierdie komponente word verreken deur teoriee van leksikalisasie, korrespondensiereels en die passing tussen konstruksies en leksikale items. Die ontleding van Afrikaanse bewegingswerkwoorde spesif iseer die omvattender anali tiese apparaat wat nodig is vir die verrekening van valensie verby die punt waarvoor 'n teorie van UG voorsiening maak. Dit blyk uit hierdie analise dat die valensie van die kategorie in 'n aantal valensieraambeskrywings vir die aparte subklasse saamgevat kan word. 'n Duidelike beeld van die universele en taalspesifiekidiosinkratiese aspekte van hierdie kategorie kan in terme van hierdie valensierame aangetoon word. 'n Verdere hipotese (die onakkusatiwiteithipotese) is dat die sintaktiese verspreiding van werkwoorde ui t hulle semantiek voorspel kan word. Hierdie hipotese word getoets aan die empiriese data van Afrikaanse bewegingswerkwoorde. Hierdie bewegingswerkwoorde word in groepe geklassifiseer na gelang van ooreenstemmende semanties-pragmatiese kenmerke. Daar word getoon dat bewegingswerkwoorde met dieself de semantiespragmatiese kenmerke dieselfde valensierame het. Valensierame is daarom op sistematiese wyse uit semanties-pragmatiese kenmerke afleibaar. Sekere fasette van valensierame word egter ook bepaal deur konvensies soos profilering, en deur bereelde interaksie met 'n basiese konstruksie se argumentstruktuur. / This thesis focuses on the development of a theoretically adequate model to account for lexical valence and to provide the detail for such a model by means of an analysis of Afrikaans verbs of motion. The thesis is a response to a theory of UG which inadequately accounts for lexical valence. A theory of UG is concerned with the universal syntactic form of a construction that is legible on LF level. It therefore describes valence in universal syntactic-categorial terms only. This thesis develops the semantic and pragmatic components of a theory of valence in order that a clearer understanding may be gained of the interaction between all the variables of valence on a language specific LF level. A theory of valence is construed eclectically from several other theories. TGG models provide the methods used to describe the syntactic component of a theory of valence. Conceptual Semantics contributes to the development of the semantic component, and models of cognitive grammar to the pragmatic component. The interaction between these components is explained by theories of lexicalisation, rules of correspondence and the fusion of constructions and lexical items. The analysis of Afrikaans verbs of motion provides the comprehensive set of analytical devices required to account for valence beyond the point of LF. From this analysis it emerges that the valence of this category can be summarized in a finite number of frames of valence for distinct classes within the category. 'n Clear understanding of the universal and language specific aspects of this category is achieved by means of these frames of valence. A further hypothesis (the unaccusativity hypothesis) posits that the syntactic distribution of verbs can be predicted from their semantics. This hypothesis is tested by means of empirical data of Afrikaans verbs of motion. These verbs are classified according to similar semantic-pragmatic features. It is shown that verbs of motion with the same semanticpragmatic features share frames of valence. These frames thus are deducible systematically from semantic-pragmatic features. Certain aspects of frames of valence, however, are determined by conventions such as profiling and the regulated interaction between verbs and constructions. / Afrikaans / D.Litt. et Phil.

This study investigates undergraduate students’ vocabulary size, and their use of formulaic language. Using the Vocabulary Levels Test (Laufer and Nation 1995), it measures the vocabulary size of native and non-native speakers of English and explores relationships between this and course of study, gender, age and home language, and their academic performance. A corpus linguistic approach is then applied to compare student writers’ uses of three high-frequency verbs (have, make and take) relative to expert writers. Multiword units (MWUs) featuring these verbs are identified and analysed, focusing on delexical MWUs as one very specific aspect of depth of vocabulary knowledge. Student and expert use of these MWUs is compared. Grammatically and semantically deviant MWUs are also analysed. Finally, relationships between the size and depth of students’ vocabulary knowledge, and between the latter and academic performance, are explored. Findings reveal that Literature students had larger vocabularies than Law students, females knew more words than males, and older students knew more than younger ones. Importantly, results indicated a relationship between vocabulary size and academic performance. Literature students produced more correct MWUs and fewer errors than Law students. Correlations suggest that the smaller students’ vocabulary, the poorer the depth of their vocabulary is likely to be. Although no robust relationship between vocabulary depth and academic performance emerged, there was evidence of an indirect link between academic performance and correct use of MWUs. In bringing together traditional methods of measuring vocabulary size with an investigation of depth of vocabulary knowledge using corpus analysis methods, this study provides further evidence of the importance of vocabulary knowledge to academic performance. It contributes to debates on the value of a sound knowledge of high-frequency vocabulary and a developing knowledge of at least 5000 words to academic performance, and the analysis and quantification of errors in MWUs adds to our understanding of novice writers’ difficulties with these combinations. The study also explores new ways of investigating relationships between size and depth of vocabulary knowledge, and between depth of vocabulary knowledge and academic performance. / Linguistics and Modern Languages / D.

Notre recherche porte sur l'analyse linguistique du verbe français et ses correspondants dans la langue arabe, dans le cadre d'une approche contrastive et comparative, pour leur intégration dans le système informatique NooJ pour une application de traduction automatique. Dans la première partie, nous avons présenté les assises théoriques sur lesquelles nous avons fondé notre étude des caractéristiques sémantico-syntaxiques des classes verbales de mouvement et de communication et qui sont essentiellement la théorie des classes d'objets de Gaston Gross et la classification des verbes français de JD & FD-C. Selon ces deux théories déjà présentées dans cette partie, nous allons faire une comparaison entre les prédicats des deux classes avec leurs correspondants en langue arabe dont nous avons donné déjà ses caractéristiques linguistiques, dans le troisième chapitre de cette partie.Dans la deuxième partie, nous avons suivi une démarche analytique mais en même temps comparative entre les deux systèmes verbaux : français-arabe. Dans le premier chapitre, nous avons effectué une comparaison entre les modes et les temps dans les deux langues. Dans les deux derniers chapitres, nous avons étudié les spécificités sémantico-syntaxiques des deux classes de communication et de mouvement entrée/sortie dont le sujet est humain [N0hum] selon la classification des « verbes français (LVF) » de JD & FD-C. Par cette analyse sémantico-syntaxique, nous avons essayé de démonter les différents patrons syntaxiques des deux classes avec la précision pour chaque type syntaxique la nature sémantique et le type de ses arguments nécessaires sans oublier de donner pour chaque prédicat son équivalent en langue arabe et faire une comparaison entre la structure argumentale des verbes français et celle des verbes arabes, pour en ressortir enfin les ressemblances et les divergences entre les deux systèmes verbaux. Et enfin, dans la troisième partie, nous avons essayé de montrer toutes les étapes nécessaires pour l'élaboration de notre application de traduction automatique en utilisant la plate-forme NooJ. Dans cette étape, nous avons créé :1/ Deux dictionnaires bilingues des verbes de communication et de mouvement. 2/ Des grammaires formelles pour la réalisation de la phase d'analyse et de reconnaissance des patrons syntaxiques des prédicats de la classe C et la classe E. 3/ Des grammaires de traduction des verbes à la forme affirmative ou négative aux temps convenables tout en précisant les règles de flexion et de l'accord en genre et en nombre selon les normes de la langue arabe.A la sortie de notre outil de traduction, nous trouvons des verbes traduits et fléchis en arabe et qui respectent les règles de la langue cible. / This research focuses on the linguistic analysis of the French verb and its correspondents in Arabic, using a contrastive and comparative approach, to integrate them into the NooJ computer system for an application of machine translation. In the first part, we have presented the theoretical foundations on which we have based our study of the semantic-syntactic characteristics of the verb classes of motion and of communication and which are essentially the Theory of the Classes of Objects of Gaston Gross and the classification of the French verbs by JD & FD-C. According to these two theories already presented in this section, we will make a comparison between the predicates of the two classes with their correspondents in Arabic to which we have already given their linguistic characteristics in the third chapter of this part. In the second part, we have followed an analytical but at the same time comparative approach between the two verb systems: French-Arabic. In the first chapter, we have compared the modes and tenses in both languages. In the last two chapters, we have studied the semantic-syntactic input / output specificities of the two classes of communication and of motion whose subject is human [N0hum] according to the classification of the French verbs (LVF) of JD & FD­ C . [n this semantic-syntactic analysis, we have tried to disassemble the different syntactic patterns of the two classes, by indicating, for each syntactic type, the semantic nature and the type of its necessary arguments without forgetting to give to each predicate its equivalent in Arabic and to make a comparison between the argumentative structure of the French verbs and that of the Arabic verbs, in order finally to corne out with the similarities and the divergences between the two verb systems.And finally, in the third part, we have tried to show al! the necessary steps for the development of our application of machine translation using the NooJ platform .In this step, we have created:1/ Two bilingual dictionaries of communication and motion verbs. 2/ Formal grammars for the realization of the analysis phase and the recognition of the syntactic patterns of the predicates of class C and class E. 3/ Grammars of translation of verbs in the affirmative or negative form at the appropriate tenses, while specifying the rules of inflection and agreement in gender and number according to the standards of Arabic. At the output of our translation tool, we have found translated and inflected Arabic verbs that respect the rules of the target language.

This dissertation deals with the variation between the conditional and the pastimperfect indicative in conditional sentences beginning with the conjunction "if". The usage of these verb tenses alternate with simple verb constructions and verbal locutions. The author aimed to detect whether the verb forms actually alternate and the factors that determine which verb forms should be used. For the purpose of this work,linguistic factors have been analysed: size of constructions, order of sentences and formal parallelism. Besides, extra-linguistic factors such as social class and age group have also been investigated. The researcher worked with a corpus that represented the language spoken in Uberlândia, Brazil. This corpus was composed by 45 interviews with adult speakers from the city mentioned previously. The perspective of Labovian Sociolinguistics (Theory of Variation) and Parametric Sociolinguistics conducted the methodology of the research. This study shows that the past imperfect indicative is mostly used among low class and the formal parallelism favours one of the verb forms analyseds. / Esta dissertação trata da variação entre o futuro do pretérito e o pretérito imperfeito do indicativo, em orações condicionais iniciadas por "se". Essas formas verbais se alternam tanto em construções com verbos simples como em locuções verbais. Buscou-se detectar se essas formas verbais se alternam e quais fatores condicionam o uso de uma em detrimento da outra. Para tanto, foram investigados fatores lingüísticos, tais como, tamanho das orações, ordem das sentenças e paralelismo formal. Além disso, foram analisados fatores extralingüísticos, como classe social e faixa etária. Para o desenvolvimento da pesquisa, trabalhou-se com um corpus representante da língua falada na cidade de Uberlândia, Brasil. Na composição desse corpus, foram utilizadas 45 entrevistas realizadas com falantes adultos desta cidade. Trabalhou-se na perspectiva da Sociolingüística Laboviana (Teoria da Variação) e da Sociolingüística Paramétrica. A análise realizada evidenciou que o pretérito imperfeito é o tempo verbal preferencial da classe baixa e que o paralelismo formal favorece um dos tempos verbais analisados. / Mestre em Lingüística
