漢語多義詞「跑」之結構及語意分析 / A structural and semantic analysis of the polysemous verb PAO in Mandarin Chinese

蔡宛玲, Tsai, Wan-Ling Unknown Date (has links)
一詞多義是所有語言會出現的共有現象,然而,過往較少探討多義詞整體結構與其各義項間的關聯,也鮮少討論句法結構延伸的原因。本篇研究將探討漢語日常使用頻率較高的移動動詞「跑」的多義性,以中研院語料庫之語料為本,客觀的回歸到語言事實作分析,並參照Talmy(1975, 1985, 2000)提出的移動事件框架,檢視「跑」所體現的概念結構及句法結構間的關聯,試圖解釋造成不及物用法至非常規賓語用法背後所展現的機制,此外,本文根據教育部重編國語辭典、中文詞彙網絡知識庫內「跑」的定義及參照Evans(2005)的原則性多義理論,確立「跑」的獨立義項並探討概念結構中不同元素的變化和「跑」多義性之間的關聯,進一步地說明各義項間的相關性與區別性,最後,參照Lakoff(1987)的放射形範疇結構整理出屬於「跑」的語意網絡圖。 本篇研究結果顯示,「跑」共有四種不同的句法結構,分別為最典型的不及物﹝A.名詞短語+跑﹞句式,由趨向介詞帶出名詞短語的﹝B.名詞短語+處所/趨向介詞+名詞短語+跑﹞句式及﹝C.名詞短語+跑+處所/趨向介詞+名詞短語﹞句式、從不及物用法延伸至非常規賓語用法的﹝D.名詞短語+跑+名詞短語(斜格)﹞句式,各句式映射到的概念結構皆不同,是概念結構內不同要素的變化影響句法結構的改變,人類的自然認知過程使路徑延伸出不同種類,造成「跑」的非常規賓語用法以及延伸出不同於字面義的其他義項。此外,本文確立「跑」的七個獨立義項為「以兩腿交互快速向前移動」義、「往特定目標移動」義、「為某事忙碌奔走」義、「迅速離開、逃走、躲避」義、「兩個以上的參與者競速」義、「交通工具或物體的移動」義及「離開原有的位置」義,各義項的出現與整體句法結構、概念結構及語境有很大的關聯,總結來說,「跑」所體現的概念結構、句法結構及語意三者之間的相互影響是造成多義現象的重要因素。 / This study investigates the prevalently used polysemous motion verb PAO “run” in Mandarin Chinese. The data are extracted from Academic Sinica Balanced Corpus of Modern Chinese. Under the framework of Motion Event Frame (Talmy 1975, 1985, 2000), the study explicates the mechanism of PAO’s syntactic complexities in a more plausible manner. Four different structures of PAO are detected: the most typical intransitive structure [A. NP+PAO], structures with prepostions [B. NP+P+PAO+NP] and [C. NP+PAO+P+NP], and the unconventional transtive structure [D. NP+PAO+NP(oblique case)]. Each structure manifests different conceptual structures. It is claimed that the extention of Path has caused the usage of unconventional transtive structure and the polysemous phenomenon of PAO. In addition, this paper investigates the relationship between the different senses of PAO and elements in its conceptual structure. The relevance and distinction between the different senses of PAO are built as a radial categorization. PAO is suggested to have seven different senses: move quickly with legs, move to specific places, move for specific reasons, escape, two or more participants race, vehicles or objects move and leave the original location. Each sense is related to the overall syntactic structure, the conceptual structure and different contexts. In conclusion, the interaction between the conceputual structure, the syntactic structure and semantic meanings is a major factor that makes a polysemy.

Caractérisation phonétique et phonologique du syntagme intermédiaire en français : de la production à la perception

Michelas, Amandine 04 July 2011 (has links)
Le travail présenté ici est sous-tendu par deux observations majeures. Premièrement, la plupart des modèles proposés pour le français s’accordent sur l’existence de deux niveaux de structure prosodique: le syntagme accentuel et le syntagme intonatif. Deuxièmement, bien que l’existence d’un niveau additionnel de structure situé entre ces deux niveaux ait été proposé pour le français, les propriétés phonétiques et phonologiques de ce constituant n’ont pas clairement été définies. Dans cette thèse nous avons fourni des preuves de l’existence du syntagme intermédiaire (ip) à la fois en production et en perception de la parole. Grâce à cinq expérimentations menées dans le cadre de la phonologie de laboratoire, nous avons caractérisé les propriétés phonético-phonologiques de ce constituant et attesté de son rôle dans le traitement perceptif du langage. Les résultats obtenus en production montrent que l’ip est le domaine de l’abaissement des accents mélodiques en français. Sa frontière droite est marquée par un allongement pré-frontière ainsi qu’un accent de syntagme responsable du retour à la ligne de référence du registre. Les analyses menées en perception ont montré que les frontières droites du syntagme accentuel et du syntagme intermédiaire sont utilisées très tôt dans le processus de traitement syntaxique. Les indices phonétiques et phonologiques présents à ces frontières permettent aux auditeurs du français de construire des attentes sur la structure syntaxique des énoncés perçus. Une analyse séparée des différents types d’indices acoustiques a également montré qu’en l’absence de marquage tonal, les indices de durée semblent suffisants dans le but de marquer la frontière de syntagme accentuel. Un marquage conjoint de la frontière droite d’ip par les indices mélodiques et l’allongement pré-frontière semble au contraire nécessaire pour que les auditeurs du français perçoivent et utilisent cette frontière dans le traitement du langage. / The work described here is grounded by two major observations. Firstly, most of the French intonation models agree on the existence of two levels of prosodic phrasing: the accentual phrase and the intonation phrase. Secondly, although the existence of an additional level of structure ranked between these two levels has been proposed for French, the phonetic and phonological properties of this intermediate phrase (ip) have not been clearly defined. In this thesis we provide evidence for the existence of an intermediate level of phrasing in French through both speech production and perception studies. Results of five experiments conducted within the framework of laboratory phonology revealed specific ip phonetic and phonological properties and tested its role in the perceptual processing of language. The production studies showed that the ip is the domain of downstep in French and that its right boundary is marked by a phrase accent responsible for a return to the register reference line. Analyses conducted in perception showed that the accentual phrase and intermediate phrase right boundaries are used early in the syntactic processing. Phonetic and phonological indices at these boundaries allow French listeners to build expectations about the syntactic structure of spoken utterances. A separate analysis of different types of acoustic cues showed that without tonal marking, pre-boundary lengthening seems to be sufficient to mark the accentual phrase boundary. Joint marking through melodic and lengthening cues appears to be necessary to perceive and make use of the ip boundary in language processing.

Uso de informação linguística e análise de conceitos formais no aprendizado de ontologias / Use of linguistic information and formal concept analysis for ontology learning.

Carlos Eduardo Atencio Torres 08 October 2012 (has links)
Na atualidade, o interesse pelo uso de ontologias tem sido incrementado. No entanto, o processo de construção pode ser custoso em termos de tempo. Para uma ontologia ser construída, precisa-se de um especialista com conhecimentos de um editor de ontologias. Com a finalidade de reduzir tal processo de construção pelo especialista, analisamos e propomos um método para realizar aprendizado de ontologias (AO) de forma supervisionada. O presente trabalho consiste em uma abordagem combinada de diferentes técnicas no AO. Primeiro, usamos uma técnica estatística chamada C/NC-values, acompanhada da ferramenta Cogroo, para extrair os termos mais representativos do texto. Esses termos são considerados por sua vez como conceitos. Projetamos também uma gramática de restrições (GR), com base na informação linguística do Português, com o objetivo de reconhecer e estabelecer relações entre conceitos. Para poder enriquecer a informação na ontologia, usamos a análise de conceitos formais (ACF) com o objetivo de identificar possíveis superconceitos entre dois conceitos. Finalmente, extraímos ontologias para os textos de três temas, submetendo-as à avaliação dos especialistas na área. Um web site foi feito para tornar o processo de avaliação mais amigável para os avaliadores e usamos o questionário de marcos de características proposto pelo método OntoMetrics. Os resultados mostram que nosso método provê um ponto de partida aceitável para a construção de ontologias. / Nowadays, the interest in the use of ontologies has increased, nevertheless, the process of ontology construction can be very time consuming. To build an ontology, we need a domain expert with knowledge in an ontology editor. In order to reduce the time needed by the expert, we propose and analyse a supervised ontology learning (OL) method. The present work consists of a combined approach of different techniques in OL. First, we use a statistic technique called C/NC-values, with the help of the Cogroo tool, to extract the most significant terms. These terms are considered as concepts consequently. We also design a constraint grammar (CG) based in linguistic information of Portuguese to recognize relations between concepts. To enrich the ontology information, we use the formal concept analysis (FCA) in order to discover a parent for a set of concepts. In order to evaluate the method, we have extracted ontologies from text on three different domains and tested them with corresponding experts. A web site was built to make the evaluation process friendlier for the experts and we used an evaluation framework proposed in the OntoMetrics method. The results show that our method provides an acceptable starting point for the construction of ontologies.

Induction, Training, and Parsing Strategies beyond Context-free Grammars

Gebhardt, Kilian 03 July 2020 (has links)
This thesis considers the problem of assigning a sentence its syntactic structure, which may be discontinuous. It proposes a class of models based on probabilistic grammars that are obtained by the automatic refinement of a given grammar. Different strategies for parsing with a refined grammar are developed. The induction, refinement, and application of two types of grammars (linear context-free rewriting systems and hybrid grammars) are evaluated empirically on two German and one Dutch corpus.

Verbing and nouning in French : toward an ecologically valid approach to sentence processing

Fromont, Lauren A. 05 1900 (has links)
La présente thèse utilise la technique des potentiels évoqués afin d’étudier les méchanismes neurocognitifs qui sous-tendent la compréhension de la phrase. Plus particulièrement, cette recherche vise à clarifier l’interaction entre les processus syntaxiques et sémantiques chez les locuteurs natifs et les apprenants d’une deuxième langue (L2). Le modèle “syntaxe en premier” (Friederici, 2002, 2011) prédit que les catégories syntaxiques sont analysées de façon précoce: ce stade est reflété par la composante ELAN (Early anterior negativity, Négativité antérieure gauche), qui est induite par les erreurs de catégorie syntaxique. De plus, ces erreurs semblent empêcher l’apparition de la composante N400 qui reflète les processus lexico-sémantiques. Ce phénomène est défini comme le bloquage sémantique (Friederici et al., 1999). Cependant, la plupart des études qui observent la ELAN utilisent des protocoles expérimentaux problématiques dans lesquels les différences entre les contextes qui précèdent la cible pourraient être à l’origine de résultats fallacieux expliquant à la fois l’apparente “ELAN” et l’absence de N400 (Steinhauer & Drury, 2012). La première étude rééevalue l’approche de la “syntaxe en premier” en adoptant un paradigme expériemental novateur en français qui introduit des erreurs de catégorie syntaxique et les anomalies de sémantique lexicale. Ce dessin expérimental équilibré contrôle à la fois le mot-cible (nom vs. verbe) et le contexte qui le précède. Les résultats récoltés auprès de locuteurs natifs du français québécois ont révélé un complexe N400-P600 en réponse à toutes les anomalies, en contradiction avec les prédictions du modèle de Friederici. Les effets additifs des manipulations syntaxique et sémantique sur la N400 suggèrent la détection d’une incohérence entre la racine du mot qui avait été prédite et la cible, d’une part, et l’activation lexico-sémantique, d’autre part. Les réponses individuelles se sont pas caractérisées par une dominance vers la N400 ou la P600: au contraire, une onde biphasique est présente chez la majorité des participants. Cette activation peut donc être considérée comme un index fiable des mécanismes qui sous-tendent le traitement des structures syntagmatiques. La deuxième étude se concentre sur les même processus chez les apprenants tardifs du français L2. L’hypothèse de la convergence (Green, 2003 ; Steinhauer, 2014) prédit que les apprenants d’une L2, s’ils atteignent un niveau avancé, mettent en place des processus de traitement en ligne similaires aux locuteurs natifs. Cependant, il est difficile de considérer en même temps un grand nombre de facteurs qui se rapportent à leurs compétences linguistiques, à l’exposition à la L2 et à l’âge d’acquisition. Cette étude continue d’explorer les différences inter-individuelles en modélisant les données de potentiels-évoqués avec les Forêts aléatoires, qui ont révélé que le pourcentage d’explosition au français ansi que le niveau de langue sont les prédicteurs les plus fiables pour expliquer les réponses électrophysiologiques des participants. Plus ceux-ci sont élevés, plus l’amplitude des composantes N400 et P600 augmente, ce qui confirme en partie les prédictions faites par l’hypothèse de la convergence. En conclusion, le modèle de la “syntaxe en premier” n’est pas viable et doit être remplacé. Nous suggérons un nouveau paradigme basé sur une approche prédictive, où les informations sémantiques et syntaxiques sont activées en parallèle dans un premier temps, puis intégrées via un recrutement de mécanismes contrôlés. Ces derniers sont modérés par les capacités inter-individuelles reflétées par l’exposition et la performance. / The present thesis uses event-related potentials (ERPs) to investigate neurocognitve mechanisms underlying sentence comprehension. In particular, these two experiments seek to clarify the interplay between syntactic and semantic processes in native speakers and second language learners. Friederici’s (2002, 2011) “syntax-first” model predicts that syntactic categories are analyzed at the earliest stages of speech perception reflected by the ELAN (Early left anterior negativity), reported for syntactic category violations. Further, syntactic category violations seem to prevent the appearance of N400s (linked to lexical-semantic processing), a phenomenon known as “semantic blocking” (Friederici et al., 1999). However, a review article by Steinhauer and Drury (2012) argued that most ELAN studies used flawed designs, where pre-target context differences may have caused ELAN-like artifacts as well as the absence of N400s. The first study reevaluates syntax-first approaches to sentence processing by implementing a novel paradigm in French that included correct sentences, pure syntactic category violations, lexical-semantic anomalies, and combined anomalies. This balanced design systematically controlled for target word (noun vs. verb) and the context immediately preceding it. Group results from native speakers of Quebec French revealed an N400-P600 complex in response to all anomalous conditions, providing strong evidence against the syntax-first and semantic blocking hypotheses. Additive effects of syntactic category and lexical-semantic anomalies on the N400 may reflect a mismatch detection between a predicted word-stem and the actual target, in parallel with lexical-semantic retrieval. An interactive rather than additive effect on the P600 reveals that the same neurocognitive resources are recruited for syntactic and semantic integration. Analyses of individual data showed that participants did not rely on one single cognitive mechanism reflected by either the N400 or the P600 effect but on both, suggesting that the biphasic N400-P600 ERP wave can indeed be considered to be an index of phrase-structure violation processing in most individuals. The second study investigates the underlying mechanisms of phrase-structure building in late second language learners of French. The convergence hypothesis (Green, 2003; Steinhauer, 2014) predicts that second language learners can achieve native-like online- processing with sufficient proficiency. However, considering together different factors that relate to proficiency, exposure, and age of acquisition has proven challenging. This study further explores individual data modeling using a Random Forests approach. It revealed that daily usage and proficiency are the most reliable predictors in explaining the ERP responses, with N400 and P600 effects getting larger as these variables increased, partly confirming and extending the convergence hypothesis. This thesis demonstrates that the “syntax-first” model is not viable and should be replaced. A new account is suggested, based on predictive approaches, where semantic and syntactic information are first used in parallel to facilitate retrieval, and then controlled mechanisms are recruited to analyze sentences at the interface of syntax and semantics. Those mechanisms are mediated by inter-individual abilities reflected by language exposure and performance.

IMPLICITLY PRIMING SENTENCE PRODUCTION IN PERSONS WITH APHASIA USING A COMPREHENSION TASK

Briana Cox (11159904) 22 July 2021 (has links)
<div>Background: Structural priming – a tendency to reuse previously encountered sentence structures – has been shown to facilitate production of sentences in persons with aphasia (PWA). However, the task-specific and person-specific factors that modulate the strength of priming effects in PWA remain largely unknown. This study examined (a) if PWA and healthy older adults (HOA) demonstrate improved production of passive sentences following comprehension of passive (as opposed to active) prime sentences, (b) whether repeated use of a verb between a prime and target sentence boosts priming effects, and (c) whether individual participants’ deficits in syntactic processing modulate degrees of priming effects.</div><div><br></div><div>Method: The participants (16 HOA and 13 PWA) completed a comprehension-to-production structural priming task. For prime sentences, they completed a sentence-to-picture matching comprehension task. Then, they described a target action picture, which could be described in an active or passive sentence structure. For half of the prime-target pairs, the verb was repeated to compare the priming effects in the same vs. different verb prime conditions (i.e., lexical boost). To analyze individual variability, we examined if PWA’s scores on clinical measures of syntactic comprehension and production were associated with a positive priming effect.</div><div><br></div><div>Results: Both HOA and PWA showed increased production of passive sentences following comprehension of passive primes, although the priming effect was reduced for PWA. A significant lexical boost was found in HOA, but not for PWA. Within PWA, individuals with higher scores on clinical measures of syntactic production, but not syntactic comprehension, showed a significant priming effect.</div><div><br></div><div>Conclusion: The findings suggest that implicit comprehension-to-production structural priming is preserved in aphasia and that lexically-mediated structural priming may not be critical to effectiveness of structural priming in aphasia. Preliminary results indicate that individuals’ syntactic skills in the domain of production may need to be considered when comprehension-to-production priming is used to improve sentence production.</div>

Language Background and the Realization of the Information Structure Constraints on English Ditransitive Constructions: Evidence from Monolingual and Bilingual Speakers

Joshua David Weirick (10948092) 23 July 2021 (has links)
<p>Previous research has shown that the type of ditransitive sentence preferred by English speakers in a particular linguistic context is significantly influenced by the relative ‘givenness’ of the post verbal arguments (i.e. the assumption that the referent of a linguistic expression is known to the speaker/hearer). This ‘givenness constraint’ has also been shown to play a role in the ditransitive sentence preferences of bilingual English speakers. Some have claimed that the realization of the givenness constraint in the ditransitive sentence preferences of bilingual English speakers is significantly influenced by the characteristics of their dominant language; however, no studies that I am aware of have explicitly compared the preferences of speakers whose dominant languages feature different sets of ditransitive sentence types, making this claim difficult to evaluate. Additionally, the effects of task type (i.e. the experimental task(s) employed by a particular study), and variables related to speakers’ experience with English and English proficiency, relative to language background are unclear. This study attempts to clarify the role of language background in the realization of the givenness constraint by recruiting three groups of English speakers: German-English bilingual speakers living in Germany, Spanish-English bilingual speakers living in Mexico, and monolingual English speakers living in the United States. The three groups completed three tasks, all of which were administered over the internet: a scalar acceptability judgement task, a forced choice task, and a self-paced reading task. The results from the two bilingual groups showed significant effects of language background, even after factors related to English proficiency and English experience were taken into account. The results support an interpretation where language background plays a significant role in the realization of the givenness constraint on bilingual speakers’ ditransitive sentence preferences. </p>

Rozvíjení komunikační kompetence pomocí online diskusních úkolů: počítačem zprostředkovaná komunikace a dovednost psaní / Developing communicative competence through online discussion tasks: computer mediated communication and the skill of writing

Tůma, František January 2012 (has links)
This dissertation deals with the developing and development of EFL learners' communicative competence in writing in a blended learning course. The dissertation addresses issues related to the conceptualization of developing communicative competence and measuring learners' progress as well as using ICT in foreign language teaching. The underlying research question was whether learners' communicative competence changed after using a series of online discussion tasks, and if so, in what manner. The empirical research was conducted as a case study in which 18 learners in an EFL course at the CEFR A2 level participated in three discussion tasks conducted online, using asynchronous discussion forum. The discussions were built on social constructivist learning theories. Methods of data collection and analysis included pre- and post-tests, learner corpus compiled from the texts written by the students in two online discussions and its analysis, and a questionnaire survey. The results showed that learners' overall level of communicative competence in writing improved. Specifically, the syntactic complexity of learners' language produced at the beginning and at the end of the course increased and learners' perceived fluency in writing improved. These findings support the claim that learners' active participation in...

El complemento de régimen verbal : construcción y distribución en español actual

Casanova Romero, Vanessa 06 1900 (has links)
Cette étude porte sur le complément de régime (CR) des verbes espagnols, du point de vue de la variation grammaticale. Les descriptions actuelles caractérisent le CR comme une fonction syntaxique argumentative, mais aucun critère formel définitif ne permet son identification systématique. Ce complément est défini comme un groupe prépositionnel sélectionné par le prédicat. Cette définition tient compte à la fois des propriétés lexicales (la rection prépositionnelle) et syntaxiques (la forme « préposition + terme ») du CR. La similitude fonctionnelle et formelle entre le CR et d’autres fonctions syntaxiques, telles que le complément direct du verbe (CD) et le complément circonstanciel (CC), ainsi que les alternances syntaxiques et prépositionnelles impliquant le CR, reflètent la complexité de notre objet d’étude. Pour déterminer le statut grammatical et la variation (alternances prépositionnelles et de construction) du CR, nous avons conçu notre recherche à partir des données dialectales de l’espagnol contemporain. Le point de départ du projet a été la confection d’une liste de verbes prépositionnels, de laquelle nous avons tiré une sélection de huit prédicats verbaux représentatifs des différents types de verbes qui exigent un CR : confiar (‘avoir confiance en’), admirar(se) (‘admirer’), corresponder(se) (‘correspondre à’), asomar(se) (‘regarder par’), atar (‘nouer’), tachar (‘accuser de’), insistir (‘insister sur’) et consistir (‘consister à’). Avec les données obtenues nous avons aussi testé les critères syntaxiques et sémantiques d’identification du CR. Les résultats nous permettent de confirmer, d’une part, les alternances syntaxiques et prépositionnelles déjà connues, mais aussi d’autres tendances caractéristiques de l’espagnol dialectal. Nos résultats suggèrent une variation morphosyntaxique beaucoup plus complexe que celle qui avait été signalée par le passé. En général, les données montrent que le CR prend part à différents processus grammaticaux : la transitivisation (insistir en algo > insistir Ø algo ‘insister sur quelque chose > insister Ø quelque chose’), intransitivisation (admirar a alguien > admirarse de alguien ‘admirer quelqu’un > s’admirer [de] quelqu’un’) et adverbialisation (atar algo al árbol > atarlo allí ‘nouer quelque chose à l’arbre > l’y nouer’). Certains de ces processus comprennent aussi des innovations grammaticales. Bien que ces innovations semblent se limiter à certaines variétés vernaculaires (confiar en mí ~ confiar mío ‘avoir confiance en moi ~ *avoir confiance mien’, consistir {en ~ de ~ Ø} + que ‘consister {à ~ *de ~ *Ø} quelque chose’), elles reflètent quand même les possibilités du système linguistique. D’autre part, le comportement de la préposition montre des tendances liées non seulement à la variation, à la fixation ou à la désémantisation, mais aussi à la disparition en tant qu’indice fonctionnel. Immergé dans les processus de grammaticalisation susmentionnés, le CR se trouve présentement dans un statut fonctionnel « liminal », semblable non seulement à celui du CD et du CC, mais également à celui du complément indirect du verbe (confiar algo a alguien ~ confiar algo en alguien ‘confier quelque chose à quelqu’un ~ confier quelque chose en quelqu’un’) et du complément prédicatif (tacharlo de ingenuo ~ tacharlo ingenuo ‘le traiter d’idiot ~ le traiter idiot’). Nous concluons que la description actuelle du CR devrait prendre en compte les processus grammaticaux qui permettent d’expliquer la variation morphosyntaxique de cette fonction syntaxique ainsi que sa proximité fonctionnelle aux autres compléments du prédicat verbal. / This study focuses on the governed prepositional object, known in Spanish as ‘complemento de régimen verbal’ (CR), from the perspective of grammar variation. Previous descriptions have shown that, despite it being recognized as a verbal complement, no syntactic criteria have proved useful for the CR’s identification yet. When defined as a ‘prepositional phrase selected by the predicate’, the CR implies both lexical (government) and syntactic (the schema ‘preposition + phrase’) properties. Its functional and formal similarities with other complements, such as the direct object (CD) and circumstantial object (CC), as well as the syntactic alternations in which it is involved, reflect the complexity behind this phenomenon. To determine the grammatical status of this complement, as well as its variation (syntactic and prepositional alternations), I designed a corpora-based study with contemporary Spanish examples. The first step was to build a list of prepositional verbs, from which I obtained a selection of eight verbal predicates representing various types of verbs that require a CR: confiar (‘to trust’), admirar(se) (‘to admire’), corresponder(se) (‘to correspond with’), asomar(se) (‘to peek in’), atar (‘to tie’), tachar (‘to label’), insistir (‘to insist’) y consistir (‘to consist of’). The sample retrieved from the databases allowed to test the syntactic and semantic criteria used for identifying the CR. Not only do the results confirm the syntactic and prepositional alternations that were already well-known, but they also reveal some uses, in dialectal Spanish, that point to a more complex variation. In general, the data shows that the CR takes part in various grammatical processes: transitivization (insistir en algo > insistir Ø algo ‘to insist on something > to insist Ø something’), intransitivization (admirar a alguien > admirarse de alguien ‘to admire someone > to admire [oneself] of someone’), and adverbialization (atar algo al árbol > atarlo allí ‘to tie something to the tree > to tie it there’). Some of these processes are linked to grammatical innovations that, in spite of being restricted to some vernacular varieties (confiar en mí ~ confiar mío ‘to trust me ~ to trust mine’; consistir {en ~ de ~ Ø} + que ‘consist {of ~ on ~ Ø} + that’), also reflect the possibilities of the language system. Moreover, the preposition that introduces the CR is prone not only to variation, fixation, and (semantical) bleaching, but even to erasing. In these processes, the CR exhibits a ‘liminal’ functional status, similar to the CD and the CC, and sometimes even closer to the indirect object (confiar algo a alguien ~ confiar algo en alguien ‘to trust something to somebody ~ to trust something on somebody’) and the predicative complement (tacharlo de tonto ~ tacharlo tonto ‘label him as silly ~ label him silly’). In conclusion, the current grammatical accounts should consider the grammaticalization processes involving the CR that allow for an explanation of its morphosyntactic variation and functional closeness to other verbal complements. / En este trabajo se estudia el complemento de régimen verbal (CR) desde la perspectiva de la variación gramatical. Las descripciones previas han mostrado cómo, a pesar de que el CR es reconocido como una función sintáctica de naturaleza argumental, no existen criterios formales definitivos para su identificación. Su definición gramatical como grupo preposicional seleccionado por el predicado presupone la consideración de sus propiedades léxicas (la rección preposicional) a la par de sus propiedades sintácticas (la forma ‘preposición + término’). Su similitud funcional y formal con otras funciones sintácticas, como el complemento directo (CD) o el circunstancial (CC), así como las distintas alternancias en las que participa, reflejan la complejidad que hay detrás de este fenómeno. Para determinar el estatuto gramatical de este complemento y la variación que presenta (alternancias de construcción y alternancias preposicionales), se diseñó un estudio basado en datos del español actual. Se parte, para ello, de la confección de una lista de verbos preposicionales, de la cual se obtiene una selección de ocho predicados verbales representativos de los distintos tipos de verbos que requieren semánticamente un CR: confiar, admirar(se), corresponder(se), asomar(se), atar, tachar, insistir y consistir. Con la muestra obtenida, se someten a prueba, asimismo, los criterios sintáctico-semánticos de reconocimiento del CR. Los resultados del estudio permiten confirmar, por un lado, las alternancias construccionales y preposicionales ya conocidas, pero también otras tendencias propias del español dialectal que apuntan a una variación mucho más compleja. En general, los datos demuestran que el CR participa en distintos procesos gramaticales: transitivización (insistir en algo > insistir Ø algo), intransitivización (admirar a alguien > admirarse de alguien) y adverbialización (atar algo al árbol > atarlo allí). Algunos de estos procesos incluyen innovaciones gramaticales que, si bien parecen restringidas a algunas variedades vernáculas (confiar en mí ~ confiar mío; consistir {en ~ de ~ Ø} + que), reflejan las posibilidades del sistema de la lengua. Por otro lado, la preposición introductora muestra tendencias no solo a la variación, fijación y desemantización, sino incluso a la desaparición. En estos procesos de gramaticalización, el CR muestra un estatuto funcional ‘liminal’, cercano al CD y al CC, pasando por el complemento indirecto (confiar algo a alguien ~ confiar algo en alguien) y el complemento predicativo (tacharlo de ingenuo ~ tacharlo ingenuo). En síntesis, la descripción actual del CR debe tomar en cuenta los procesos gramaticales que permiten explicar su variación morfosintáctica y su cercanía funcional con otros complementos del predicado verbal.
