Spelling poses a challenge to Arabic-speaking learners due to the complexity of the morphological and orthographic systems in Arabic. Arabic morphology has been argued to play a critical role in spelling since its morphological operations are built on a system consisting of a root that is interlocking into different patterns of vowels to form…

The purpose of this research is to investigate the variable production of English Object-Experiencer (OE) psych predicates among 80 L1 Thai EFL first-year university students. Psych verbs are notable for posing difficulty for learners due to a unique property that violates Grimshaw's (1990) Thematic Hierarchy. The participants were given a cloze…

Acquisition of oral English verb morphology presents difficulties for bilinguals, learners of EFL and English-speaking monolingual children with specific language impairment. This study aimed to identify challenging English verb inflections among sixth grade speakers of Arabic (N = 85) and Hebrew (N = 86) using an elicited oral narrative task, and…

It is pertinent to observe that the vagaries of the English language grammar constitute a major problem in the teaching and learning of English in a second language situation like Nigeria. The inherent structural irregularities within the English language have made it difficult for users and learners of English to grapple with the unconventional…

The acquisition of systematic patterns and exceptions in different languages can be readily examined using the causative construction. Persian allows four types of causative structures, including one productive multiword structure (i.e. the light verb construction). In this study, we examine the development of all four structures in Persian child…

This dissertation provides a comprehensive analysis of the L2 acquisition of Spanish psych-verbs (e.g. "gustar" "to like") across four different proficiency levels. In particular, psych-verbs constitute a testing ground for the predictions of the Interface Hypothesis (Sorace and Filiaci, 2006; Tsimpli, Sorace, Heycok &…

Outside the core grammar, the set of "peripheral" or marked properties of a language include exceptions or relaxations of the settings of core grammar and the idiosyncratic features of the language governed by particular lexical items. The core/peripheral distinction has direct implications for grammatical development in children. The…

This study of 15 Hebrew-speaking preschool children with specific language impairment and 2 comparison groups tentatively supported the notion that grammatical morphemes were less difficult for subjects if they take the form of stressed and/or lengthened syllables and if they appear in a language in which nouns, verbs, and adjectives must be…

A discussion of language acquisition assumes that lexicon plays a central role, and that the principles of conventionality and contrast are also essential. It examines the hypotheses children draw on about possible word meanings and how they map their meanings into forms. This process begins with children's emerging knowledge of conventional words…
