The measurement of second language (L2) productive lexical proficiency has driven a great deal of research over the past two decades. Research has indicated that more proficient speakers and writers tend to use a wider range of words and that more proficient writers tend to use words that are more sophisticated (less frequent in reference…

The data-rich articles in this special issue invite readers to consider how grammar and multimodality enact social practices. In particular, they propose a reconceptualization of grammar, moving beyond an autonomous system of items and combinatorial rules to demonstrate how grammar is an embodied resource for social interaction. In this…

Frequency and proficiency have been found to play an important role in second language (L2) phrasal processing. However, existing research has largely focused on English and other European languages, with other commonly used languages, such as Chinese, being largely disregarded. To fill this gap, we carried out two experiments to investigate how…

The articles in this special issue contribute to understanding the interactional grounding of language learning by scrutinizing how patterns of language use emerge and get routinized as dynamic resources for accomplishing actions in co-constructed interaction. Their findings problematize how grammar is represented in second language (L2) teaching…

Evidence from usage-based studies of second language (L2) acquisition reveals that a main source of L2 learners' developing grammars is the L2 input to which learners are regularly exposed. What learners develop from their extended engagement in the sequences of actions comprising the input is not an acontextual system of grammatical units but…

The article introduces triangulation to converge evidence from corpus and experimental data, by means of two case studies in second language (L2) learners of Greek. The first case study investigates the acquisition of gender agreement, while the second probes the development of relative clauses. In both studies, findings from the corpus are tested…

Abstract In this article, we bring together conversation analysis and usage-based linguistics to investigate the second language (L2) developmental trajectory of a linguistic construction within the complex multimodal ecology of naturally occurring social interaction. We document how, over the course of 15 months, an L2 speaker's use of the French…

This study investigated the influence of teachers' experience with research-related activities on their current grammar teaching practice and research engagement for second language (L2) grammar instruction. Survey responses were collected from 701 Korean L2 English teachers and were analyzed with exploratory factor analyses and logistic…

Research examining rule formation and second language (L2) explicit knowledge during guided inductive instruction has focused on co-constructed metalanguage or depth of processing (DoP) using think-aloud protocols, but without analyzing rule features. Studies have not focused on the architecture of the rules that L2 learners create individually.…

In second language (L2) research, the lexical unit is often defined as a base word plus inflectional and derivational forms through Level 6 of Bauer and Nation's framework (WF6). WF6 use has been justified by the assumption that once a form is known, recognition of other WF6 members requires little extra effort. A more lenient view holds that an…

This study compares the effects of distributed versus massed corrective feedback (CF) on Spanish differential object marking (DOM). Forty-eight Spanish learners completed three communicative tasks with a researcher on three consecutive days, one task per day. Partial recasts were used to reformulate DOM errors. The distributed group (n = 16)…

Through either morphological or functional approaches, previous research has examined how instructed second language (L2) learners develop control over a challenging area of French: the use of the "imparfait." In order to better understand this challenge, this cross-sectional study utilized both approaches and examined how 94 university…

This systematic review synthesizes the literature (involving 62 empirical studies) regarding the effectiveness of cognitive linguistics-inspired language pedagogies (CL-ILPs) on second language (L2) learning. It begins with an overview of the main theoretical tenets of cognitive linguistics followed by a description of the data selection, coding,…

This study investigated to what extent and how novice second-language (L2) Spanish learners use the cognitive linguistics-informed concept of boundedness to support their development of aspect--namely, the Spanish preterite and imperfect. The concept was presented within the framework of concept-based instruction (CBI) as part of a regular,…

The present study investigates to what extent first-language (L1) and second-language (L2) speakers use lexical futures, whether such forms provide evidence of development, and whether these forms are constrained differently from the present indicative (PI) according to linguistic predictors. It uses a combined approach through its…
