    The study clarifies certain details of the Coptic verbal system, such as diathetic classes of labile verbs, semantic classes of non-labile mutable verbs, stative: infinitive opposition, the functional range of the periphrastic construction, integration of Greek loan verbs into Coptic valency alternation system and the role of the loaned morphology in that system. In all these problems, we find manifested the interaction between two grammatical categories, transitivity and aspect. The introductory chapter briefly states the research objectives and gives a general overview of the linguistic material and theory employed. The first chapter studies major regularities in the transitivity alternations of native Egyptian verbs. Defining the Coptic conjugation system by two parameters, aspect and transitivity, I examine the functions of the absolute infinitive as the only unmarked form opposed, on the one hand, to transitive eventive construct forms, and on the other hand, to intransitive stative. The system of conjugation patterns is analyzed as a templatic system where a specific conjugation pattern ascribes not only tense, aspect, and modus, but also voice to an unmarked verbal form. Finally, the native verbs are classified into four groups based on the formal criteria of mutability and lability, and this classification is found to correlate with the semantic one based on the agentivity and telicity of verbal lexemes. I also look into the diachrony of the aspect-transitivity cluster and use the two-parameter model to explain various synchronic anomalies of Coptic verbal valency. The second chapter looks into semantic and grammatical factors triggering the use of the periphrastic pattern which is shown to fulfil the whole range of functions, from punctual passive to resultative, depending on the lexical properties of the verb. The third chapter explores the diathesis of Greek loan verbs in Sahidic. Valency-changing devices for Greek verbs are examined and compared with those operating on native verbs. The occasional use of Greek middle-passive suffix is analyzed as the vestige of parallel system borrowing

    Transitivity and Intonation: A Preliminary Account of Transitive Lowering

    Are subjects produced differently based on the transitivity of the clause they are embedded in? Based on data from a narrative reading experiment, it is shown that transitive subjects are produced with a lower f0 than intransitive subjects and that this difference is statistically significant (p∠0.05). It is suggested that the purpose for such a difference originates from a propensity for English speakers to accent new referents, which are common in the object position. By lowering the f0 of the subject, speakers increase the efficacy of an accent on a new object later in the clause. Finally, the read narrative procedure is evaluated for its strict control of stimuli, while also reproducing known intonational phenomena

    The papers collected in this book are devoted to verbal valency, and share a diachronic perspective, by either discussing changes in the behavior of verbs or discussing verbal valency at different historical stages of specific languages. They provide new data for research on valency patterns and on changes in valency orientation, verbal voice, and related constructions

    Reflexive Space. A Constructionist Model of the Russian Reflexive Marker

    Get PDF
    This study examines the structure of the Russian Reflexive Marker ( ся/-сь) and offers a usage-based model building on Construction Grammar and a probabilistic view of linguistic structure. Traditionally, reflexive verbs are accounted for relative to non-reflexive verbs. These accounts assume that linguistic structures emerge as pairs. Furthermore, these accounts assume directionality where the semantics and structure of a reflexive verb can be derived from the non-reflexive verb. However, this directionality does not necessarily hold diachronically. Additionally, the semantics and the patterns associated with a particular reflexive verb are not always shared with the non-reflexive verb. Thus, a model is proposed that can accommodate the traditional pairs as well as for the possible deviations without postulating different systems. A random sample of 2000 instances marked with the Reflexive Marker was extracted from the Russian National Corpus and the sample used in this study contains 819 unique reflexive verbs. This study moves away from the traditional pair account and introduces the concept of Neighbor Verb. A neighbor verb exists for a reflexive verb if they share the same phonological form excluding the Reflexive Marker. It is claimed here that the Reflexive Marker constitutes a system in Russian and the relation between the reflexive and neighbor verbs constitutes a cross-paradigmatic relation. Furthermore, the relation between the reflexive and the neighbor verb is argued to be of symbolic connectivity rather than directionality. Effectively, the relation holding between particular instantiations can vary. The theoretical basis of the present study builds on this assumption. Several new variables are examined in order to systematically model variability of this symbolic connectivity, specifically the degree and strength of connectivity between items. In usage-based models, the lexicon does not constitute an unstructured list of items. Instead, items are assumed to be interconnected in a network. This interconnectedness is defined as Neighborhood in this study. Additionally, each verb carves its own niche within the Neighborhood and this interconnectedness is modeled through rhyme verbs constituting the degree of connectivity of a particular verb in the lexicon. The second component of the degree of connectivity concerns the status of a particular verb relative to its rhyme verbs. The connectivity within the neighborhood of a particular verb varies and this variability is quantified by using the Levenshtein distance. The second property of the lexical network is the strength of connectivity between items. Frequency of use has been one of the primary variables in functional linguistics used to probe this. In addition, a new variable called Constructional Entropy is introduced in this study building on information theory. It is a quantification of the amount of information carried by a particular reflexive verb in one or more argument constructions. The results of the lexical connectivity indicate that the reflexive verbs have statistically greater neighborhood distances than the neighbor verbs. This distributional property can be used to motivate the traditional observation that the reflexive verbs tend to have idiosyncratic properties. A set of argument constructions, generalizations over usage patterns, are proposed for the reflexive verbs in this study. In addition to the variables associated with the lexical connectivity, a number of variables proposed in the literature are explored and used as predictors in the model. The second part of this study introduces the use of a machine learning algorithm called Random Forests. The performance of the model indicates that it is capable, up to a degree, of disambiguating the proposed argument construction types of the Russian Reflexive Marker. Additionally, a global ranking of the predictors used in the model is offered. Finally, most construction grammars assume that argument construction form a network structure. A new method is proposed that establishes generalization over the argument constructions referred to as Linking Construction. In sum, this study explores the structural properties of the Russian Reflexive Marker and a new model is set forth that can accommodate both the traditional pairs and potential deviations from it in a principled manner.Siirretty Doriast

    Classical Arabic verb inflection: a WP-grammar, with an introductory phonemic investigation

    Get PDF
    This work presents a new grammar of the Classical Arabic Verb Inflection, carried out within the system of the WP morphological theory (the Word and Paradigm model of analysis as formalized by Professor P. H. Matthews). It is thus basically an application of this structural theory, rather than an assessment of its merits. Yet a general evaluation of characteristics of this theory, compared with two other interrelated systems, is presented with"particular attention to the concept of adequacy' in relation to Arabic grammar. The thesis consists of six chapters, the first of which represents an elaborated introduction meant to define the implicit questionable points that the title may raise. This is followed by a chapter on phonemic investigation, restricted to the problematic areas where the scholarly dispute over a specific number of Arabic phonemes has been building up since the Classical era. The terminological distinctions between the basic traditional terms of Arabic grammar and their presumed equivalents in modern linguistics is discussed in Chapter III as a prelude to the major body of the work. Chapter IV reviews, first, the three relevant linguistic models of analysis in relation to the morphology of Classical Arabic, which is taken here beyond the restrictive study of the individual language to the domain of the general linguistic theory; and, second, it presents a comprehensive summary of WP: its basic terms, rule system and evaluational procedure, followed by the reasons that made it the ideal choice for the present purpose. Chapter V, which serves as a background to the application in Chapter VI, represents the core of the discussions devoted to the Classical Arabic verbal system. It comprises all the explanations that are possibly needed for the making and understanding of the grammatical rules, and which find no room in the final chapter without interrupting the flow of the rule divisions. The final chapter is merely an application of the WP model to the inflectional system of the Classical Arabic verb. It consists of the verbal grammatical rules, preceded by a minimized group of the required guiding notes, and followed by an exemplary demonstration of the drivational system. The thesis is ended with a Summary and Conclusions that survey the work in general and briefly record its findings. In addition to the original views and postulations distributed over almost all the chapters of this work, and apart from the empirical value regarding the theory adopted, the present grammar represents on the one hand a further step in the evolutional course of the Classical Arabic grammar, and on the other it provides a new link between this classical grammar and the continual evolution of the linguistic theory

    Diversity in African languages: Selected papers from the 46th Annual Conference on African Linguistics

    Get PDF
    Diversity in African Languages contains a selection of revised papers from the 46th Annual Conference on African Linguistics, held at the University of Oregon. Most chapters focus on single languages, addressing diverse aspects of their phonology, morphology, semantics, syntax, information structure, or historical development. These chapters represent nine different genera: Mande, Gur, Kwa, Edoid, Bantu, Nilotic, Gumuzic, Cushitic, and Omotic. Other chapters investigate a mix of languages and families, moving from typological issues to sociolinguistic and inter-ethnic factors that affect language and accent switching. Some chapters are primarily descriptive, while others push forward the theoretical understanding of tone, semantic problems, discourse related structures, and other linguistic systems. The papers on Bantu languages reflect something of the internal richness and continued fascination of the family for linguists, as well as maturation of research on the family. The distribution of other papers highlights the need for intensified research into all the language families of Africa, including basic documentation, in order to comprehend linguistic diversities and convergences across the continent. In this regard, the chapter on Daats’íin (Gumuzic) stands out as the first-ever published article on this hitherto unknown and endangered language found in the Ethiopian-Sudanese border lands
