There is a growing body of research from various perspectives in heritage language (henceforth HL) acquisition as an emerging field. Some studies proposed that HL acquisition is a differential acquisition compared with the baseline language (i.e., the language spoken by the parents or caregivers) (Kupisch & Rothman, 2018; Dubiel &…

American Norwegian (AmNo), a moribund heritage variety of Norwegian spoken predominantly in the Upper Midwest of the US, licenses "wh"-infinitives (i.e. indirect questions), which are structures that are not acceptable in either standard Norwegian Bokmål or Norwegian dialects. Adopting a spanning-account of syntax (Blix, 2021; Julien,…

Due to the typological differences between Korean's aspect system and English's aspect system in terms of progressive construction "-ko iss," learners can no doubt have difficulty acquiring and using the "-ko iss" construction in learner Korean. This dissertation investigates two main points: (i) how is the "-ko iss"…

Background and aims: Although autism spectrum disorder (ASD) has not traditionally been associated with morphosyntactic impairments, some children with ASD manifest significant difficulties in this domain. Sentence Repetition (SRep) tasks are highly reliable tools for detecting morphosyntactic impairment in different languages and across various…

Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

Language is inherently variable, and learner language is particularly variable. The variationist paradigm considers learner language a heterogeneously variable yet inherently rule-governed system. Specifically, learners' alternation between native-like and nonnative-like variants of a variable or invariable target native speaker (NS) form…

This paper examined whether a younger starting age of formal instruction on a foreign language is beneficial in expanding circle countries. An experimental study was designed to examine to what extent the five varieties of English language teachers are intelligible to Japanese- (JSLs) and Korean-speaking language learners (KSLs), who have…

This article adopts the surface overlap and derivational complexity hypotheses to study crosslinguistic transfer in the adult second language (L2) acquisition of English genitive alternation (between the s-genitives and the of genitives) by intermediate and advanced Egyptian Arabic-speaking learners. While the "s"-genitive (e.g.…

Purpose: Language sample analysis is widely regarded as the gold standard of language assessment. However, the uncertainty regarding the optimal length of sample and the limited availability of developmental language data for nonmainstream languages such as Afrikaans complicate reliable use of the method. The study aimed to provide guidelines on…

This study builds on prior research on second language (L2) Spanish psych verbs, which has centered on morphosyntactic properties, by examining their syntactic distribution, which relies on lexical semantic knowledge. The fact that certain forms are licensed for some verbs, but not others, is the result of an underlying lexical semantic difference…

The present study examines the tradeoff between the on-line construction of modifier-noun gender agreement and verb-subject person/number agreement vs. the automatization and entrenchment of agreement, through the study of bilingual speakers of Spanish and the Afro-Colombian creole language Palenquero, whose lexicon is highly cognate with Spanish,…

English is a language with a rigid word order, whereas Arabic is more flexible. Canonical English word order is often a challenge for users whose first language is flexible. This study explores how Arabic learners transfer their knowledge of Arabic word order styles into the English language, and it compares Arabic learners' use of English word…

The Interface Hypothesis proposes that the pragmatic-discursive interface with syntax is more vulnerable to crosslinguistic influence than the syntactic-semantic interface [Tsimpli, Ianthi, and Antonella Sorace. 2006. "Differentiating Interfaces: L2 Performance in Syntax- Semantics and Syntax-Discourse Phenomena." In Proceedings of the…

This study investigated the predictions of two approaches to second language acquisition. According to the usage-based approach, learner knowledge results from the strengths and weaknesses of input-driven statistical learning. According to the learner-varieties approach, pragmatic communication principles and language-internal constraints play…

Loosely attached to other syntactic elements in an utterance, pragmatic markers (PM) are one of the most frequented pragmatic elements that fulfill various functions. Among a great number of PMs encountered in daily conversations, I think is one of the most prevalent PMs in native speaker and non-native speaker discourse. Thus, the purpose of this…
