What does it mean to learn a word? How can we tell when a sequence of letters or sounds becomes a word in the mind of the learner? While many second language (L2) vocabulary teaching and learning studies continue to use traditional vocabulary tests to measure learning (such as multiple choice, translation, gap-fill), these measures tend to come…

Incidental learning is a well-known process of acquiring new knowledge, vocabulary, or information without intention. Traditional or intentional learning is widely practiced in classroom environments, while incidental one receives less attention from educators, schools, and scholars. English Language Learners encounter various problems when they…

Third language (L3) lexical acquisition is still underexplored. In this article I overview theoretical and empirical evidence on L3 lexical acquisition and the role of cross-linguistic influence (CLI) in learning L3 words. I explain the mechanism of CLI as resulting from language co-activation in the multilingual learner's/user's mind.…

This article offers a critical review of research on the use of glossing and its contribution to second language (L2) vocabulary acquisition. Discussion topics include the complexity of estimating the effectiveness of glossing relative to reading non-glossed texts, the quest for optimal implementations of glossing, issues of ecological validity,…

We are encouraged by Cobb's (2022) description of changes to the Morpholex profiling tool (https://www.lextutor.ca/cgi-bin/morpho/lex/) resulting in more accurate word classifications. This addresses one point in our recent commentary on Morpholex and on Laufer and Cobb's (2020) study using Morpholex (McLean & Stoeckel, 2021). However, Cobb…

This article describes a new questionnaire, the "Diagnostic Inventory for Self-Regulated Language Learning" (DISLL), for assessing self-regulated learning strategies of students of English as an additional language. We discuss self-regulated learning models, evaluate existing questionnaires for assessing language learners' self-regulated…

Most teachers are concerned about the teaching of vocabulary. However, it is much more effective to focus on the ways in which vocabulary can be learned. This article looks at the jobs of the teacher, which include, in order of importance, (1) designing a balanced course, (2) organizing classroom work and homework, (3) training the learners in how…

This article puts forward several proposals for replicating two well-known "First Exposure" studies dealing with the earliest stages of adult second language acquisition. Both of them enquire into the word-level knowledge that complete beginners are able to extract from minimal input when exposed to a new language for the first time.…

In this review, we evaluate the claim that translanguaging in the classroom supports the development of the bilingual lexicon by enhancing cross-linguistic transfer. To address this issue, we integrate findings from psycholinguistics and educational sciences in order to identify how effective pedagogical practices for monolingual children can be…

Word stress is frequently afforded secondary importance in English teaching as stress placement rules are complex and because stress can be learnt along with each new word. However, training learners to pay more attention to word stress cues can support them in predicting the stress patterns of new vocabulary. Also, for speakers of fixed stress…

Exploring the longitudinal development of second language (L2) lexical use has been one of the important topics in L2 vocabulary research. One approach to examining longitudinal changes in L2 lexical use is to capture changes in lexical features as found in learner production, such as L2 writing, over time. To further facilitate this approach, the…

This paper aims to discuss old and contemporary perspectives in understanding language acquisition taking into account the neural theory of language. Discussing a recent theory by Kuhl (2010), neural substrates of first language learning will be put forward (Berwick et al., 2013). Neural substrates of phonetic learning, word learning, sentence…

Learning new words is fundamental in both first and second-language reading. There are, however, divided opinions on the best instructional approaches. Two widely used approaches across languages are whole-word focus and word-constituent focus. The appropriateness of each approach has varied historically, even within a single language (e.g., the…

This article proposes a novel account for the overuse of free morphemes and underuse of bound morphemes in English as a second language (L2) based on the framework of Distributed Morphology. It will be argued that an Economy Principle 'Do everything in Narrow Syntax (DENS)' operates in the L2 learner's computational system. Consequently,…

This research synthesis describes, critiques, and synthesizes intervention studies related to the academic vocabulary acquisition of post-secondary English learners. Using the article matrix and the constant-comparative methods of analysis (Boeije, 2002), this critical synthesis aims to provide a knowledge point on general academic vocabulary;…
