While discourse markers (DMs) are crucial for coherence and interactional competence, previous research suggests that learners' usage of DMs differs from L1 speakers. Prior research has taken either a discourse-functional or interactional approach, yet combining these two methods may provide greater understanding of the unique learner…

There has been plenty of observational evidence displaying that L2 English learners whose L1 do not have article systems undergo persistent difficulties. It is known that functional categories of grammar are especially difficult for L2 learners, and the Korean language does not have a functional equivalent to English articles. The current study…

This study attempts to explain a systematic phenomenon that has been described in interlanguage grammars crosslinguistically: Null-Prep, which consists of omitting the obligatory preposition in certain movement constructions. We propose that Null-Prep is not related to lack of knowledge of "wh"-movement, as previously assumed, but to…

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 study investigates the effects of input-based and output-based instructions on the acquisition of second language (L2) request modifiers. Four intact classes were randomly assigned to textual enhancement (TE), input flooding (IF), output-based instruction (OI), and control (CO) groups. The TE group watched some captioned videos on requests…

Learning to use prepositions in English as a second language (L2) has been widely acknowledged to pose significant difficulties to learners, especially within metaphorical contexts. Difficulties relate to the complex distributional patterns of prepositions in discourse, namely, the variety of collocations requiring their use, as well as…

Variability in the form of article (i.e., a and the) omissions and stressing has been attributed to a mismatch between first (L1) and second language (L2) prosodic and syntactic structures. An overlap between the L1 and L2 systems, on the other hand, is expected to contribute to native-like article productions. This case study aims to explore the…
