    The acquisition of gender and the development of derivational morphology in child L2 Greek

    We investigate the relationship between the acquisition of gender and derivational morphology in 124 Turkish L1 child acquirers of Greek (mean age: 13.6). Three oral elicitation tasks are used: a gender assignment task, a gender agreement task and a derivational morphology task. Results reveal that the nonnative speakers (NNS) lag behind their monolingual peers on all tasks, but have extremely low scores on the derivational morphology task. Interestingly, the correlation between their performance on the gender agreement and the derivational morphology task is higher than on the other two cases, suggesting that the NNS might be relying more on their explicit knowledge on the gender assignment task

    The three studies in this dissertation bring together quantitative and qualitative methods in order to understand L2 learning of derivational morphology. By using measures of derivational knowledge developed from L1 research, Study 1 provides a foundation for in-class research by assessing what L2 learners know and do not know about derivational morphology in comparison to adult native English speakers and how factors such as L1 background and L2 proficiency shape L2 knowledge of derivational morphology. Results show that L2 learners have poor knowledge of derivational morphology regardless of L1 background or L2 proficiency.Study 2 follows from these results and investigates the effects of input-processing versus pushed output instruction on the development of productive and receptive morphological abilities. The results of this study support the hypothesis that instruction is beneficial for L2 derivational learning; however, results do not support the hypothesis that pushed output instruction leads to better immediate and long-term learning than the input-processing condition. In fact, results suggest that equivalent learning occurs between the two conditions across all measures of derivational knowledge.Finally, Study 3 was a qualitative investigation of learners' attitudes, actions, and motivations towards the learning of derivational morphology over the course of Study 2. Using activity theory, this study describes how students' initial actions, which were not aligned with the goal of morphological learning, were transformed over the course of the study as students came to realize the importance of derivational morphology for their success in English. The results of this study are also important because they offer an alternative explanation for why the hypotheses in Study 2 regarding the effectiveness of output were not supported. Specifically, many participants in this study became aware of derivational morphology for the first time as a result of this study; therefore, a "novelty effect" (cf. Tulving & Kroll, 1995) may have overridden any potential benefit of the output treatment over the input treatment

    Context-Aware Prediction of Derivational Word-forms

    Derivational morphology is a fundamental and complex characteristic of language. In this paper we propose the new task of predicting the derivational form of a given base-form lemma that is appropriate for a given context. We present an encoder--decoder style neural network to produce a derived form character-by-character, based on its corresponding character-level representation of the base form and the context. We demonstrate that our model is able to generate valid context-sensitive derivations from known base forms, but is less accurate under a lexicon agnostic setting

    Headedness in Igbo derivational morphology

    Get PDF
    Until the 80s, the term ‘head’ was only used in syntax to describe types of phrase (endocentric phrases). It served as a central element distributionally equivalent to the phrase as a whole. During this period, little or no attention was paid to the study of complex words which themselves should also have heads, given their structure. Even on the eventual extension of the term to morphology, different scholars, as well as languages have differing assumptions about which of the affixes in a complex word should be the head. Thus, while some scholars generalised that the head would be consistently be located on the right hand side, others argue that in some languages, both left-handed and right-handed head occur. The apparent confusion generated by these arguments motivated many scholars, hence this study to determine to determine headedness in the Igbo derivational morphology. To account for the derivation of nominals and adjectives from the cognate verb sources in Igbo, the study adopted the projection principles as theoretical framework. It was finally discovered, among other things, that the Igbo verb is the most prolific lexical category in word formation in the language. Again, the study discovered and therefore posited that Igbo adopts the left-hand-head rule as a strategy in derivational morphology, contrary to the hitherto held and generalised notion of right-hand-head rule

    This study deals with derivational of morphology. This research aims to discuss theunderstanding of morphology and types of morphology, this is derivational morphem,which has same aspects suffixes and prefixes and how they are categorized. Thisresearch is descriptive qualitative. The data was gained by using literature review. Theresearcher look for the data from the internet and e-book. The result of the data are; typesof derivational morphemes are derivational prefixes (-un, -dis) while derivational suffixes (-ment, -ness, -ion, -able, -less, -en, -ize, -ly

    Development of a Hindi Lemmatizer

    We live in a translingual society, in order to communicate with people from different parts of the world we need to have an expertise in their respective languages. Learning all these languages is not at all possible; therefore we need a mechanism which can do this task for us. Machine translators have emerged as a tool which can perform this task. In order to develop a machine translator we need to develop several different rules. The very first module that comes in machine translation pipeline is morphological analysis. Stemming and lemmatization comes under morphological analysis. In this paper we have created a lemmatizer which generates rules for removing the affixes along with the addition of rules for creating a proper root word

    Derivational morphology in the German mental lexicon: A dual mechanism account

    Get PDF
    The Dual Mechanism Model posits two different cognitive mechanisms for morphologically complex word forms: decomposition of regulars into stems and exponents, and full-form storage for irregulars. Most of the research in this framework has focused on contrasts between productive and non-productive inflection. In this paper, we extend the model to derivational morphology. Our studies indicate that productive derivation shows affinities with both productive and non-productive inflection. We argue that these results support the linguistic distinction between derivation and inflection, particularly as it is represented in realization-based models of morphology
