The present study empirically scrutinizes the fixed natural order of grammatical morphemes relying on a manual analysis of an EFL learner corpus. Specifically, we test whether the accuracy order of L2 grammatical morphemes in the case of L1 Turkish speakers of English deviates from Krashen's (1977) natural order and whether proficiency levels play…

The aim of this study is twofold: to analyze politeness strategies in the online conversations of Thai students, and to suggest how this analysis can be applicable to pedagogical practice. A corpus of a 21-month instant online conversation among students and teachers has been analyzed. Throughout the time of data collection, the teachers…

This study aimed to identify second language (L2) developmental indices while controlling for the effects of first language (L1). More specifically, this study investigated the differences in the use of metadiscourse markers among learners from different L1 backgrounds. The following research questions were explored: (1) Which metadiscourse…

English and Chinese have typological differences in finiteness. English has morphological finite and nonfinite distinction, whereas Chinese has no morphological finiteness, and multiple verbs in a clause appear in the form of bare verbs with optional aspectual morphemes, such as the perfective morpheme "le". The current study explores…

This edited volume offers critical reflections on an essential component of research method in the field of second language acquisition -- data. Scholars working on diverse areas (e.g., pragmatics, corrective feedback, phonology) and approaches (e.g., corpus linguistics, concept-oriented analyses, variationism) have come together to identify…

This paper first surveys three kinds of learner interview corpora (LINDSEI, NICT-JLE Corpus, and Trinity Lancaster Corpus), paying particular attention to their interview structures. Then, it explains the principles and features of the ICNALE Spoken Dialogue (ICNALE SD), which includes 425 videos and approximately 1.6-million-word transcripts of…

Morphological complexity (MC) is a relatively new construct in second language acquisition (SLA). After critically discussing existing approaches to calculating MC in first- and second-language acquisition research, this article presents a new operationalization of the construct, the Morphological Complexity Index (MCI). The MCI is applied in two…

This article reports on the first results of a large-scale research programme that aims to define and circumscribe the construct of phraseological complexity and to theoretically and empirically demonstrate its relevance for second language theory. Within this broad agenda, the study has two main objectives. First, it investigates to what extent…

This article investigates phenomena related to subject pronoun realization in the English interlanguage of Macedonian learners. Preliminary research indicates that learners tend to omit the subject pronoun in both referential and non-referential contexts. It can be presumed that such interlanguage features are due to crosslinguistic influence,…

As learner corpora have presently become readily accessible, it is practicable to examine interlanguage errors and carry out error analysis (EA) on learner-generated texts. The data available in a learner corpus enable researchers to investigate authentic learner errors and their respective frequencies in terms of types and tokens as well as…

This paper reports the compilation of a corpus of Taiwanese students' spoken English, which is one of the sub-corpora of the Louvain International Database of Spoken English Interlanguage (LINDSEI) (Gilquin, De Cock, & Granger, 2010). LINDSEI is one of the largest corpora of learner speech. The compilation process follows the design criteria…

Heritage speakers (HSs) of Russian in the United States form a very complex and diverse group of learners. Research in heritage linguistics has examined key parameters of the HSs' oral production. Important work has been done in heritage language (HL) pragmatics, morphology, and lexicon. However, very few studies have been conducted to…
