Research has shown that non-native background languages (L2s) can play an important role in the acquisition of an L3/L[subscript n]. However, only a few studies have focussed on positive transfer from an L2 to an L3/Ln in the context of multilingual language acquisition of Romance past tenses. The present study therefore analyses the acquisition…

This article examines the relationships between second language acquisition (SLA), instructed second language acquisition (ISLA), and language teaching by examining them from the lens of the research on the acquisition and teaching of second language (L2) tense-aspect in the last 20 years (2000-2021). Review 1 examines 56 instructional effect…

Chinese learners of English often experience difficulty with English tense presumably because their native language is tenseless. We showed that this difficulty relates to their incomplete conceptual representations for tense rather than their poor grammatical rule knowledge. Participants made acceptability judgments on sentences describing…

In the past, research on the cognitive neural mechanism of second language (L2) learners' processing time information has focused on Indo-European languages. It has also focused on the temporal category expressed by morphological changes. However, there has been a lack of research on L2 learners' various time coding means, especially for Mandarin,…

The present continuous tense can be problematic among L1 Thai learners due to the variation in contexts in which the tense can be used (Boonjoon, 2017; Khattiya, 2018; Kongthai, 2015). The present study aimed to examine the functional use of the English present continuous tense by L1 Thai learners under the theoretical framework of the…

When acquiring the English plural, children correctly produce plural words long before they develop an understanding of morphological structure. When acquiring Sesotho noun prefixes, children are aware of the multiple constraints governing variation from a young age. Both of these cases raise questions about the Shin and Miller (2022) account of…

A word often expresses many different morphological functions. Which part of a word contributes to which part of the overall meaning is not always clear, which raises the question as to how such functions are learned. While linguistic studies tacitly assume the co-occurrence of cues and outcomes to suffice in learning these functions (Baer-Henney,…

The growing body of teachers' cognition research suggests that language teachers' decisions about grammar teaching are influenced by what they know, think, and believe. While previous research highlights that learning the present perfect tense is challenging for foreign language learners, little research discussed teachers' beliefs about how these…

Convergent evidence suggests that, for bilingual learners, well-developed morphological awareness in the first or second language may facilitate second language reading comprehension. However, there may be important differences between types of morphological awareness which could affect the degree to which second language reading comprehension is…

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 sheds light on the linguistic and extralinguistic conditions that determine the likelihood of L1 grammatical attrition in late sequential bilinguals. We explore whether aspectual interpretations associated with the present tense may be a vulnerable area for the native grammar of 30 late Spanish-English bilinguals who have settled in…

Previous research has indicated that explicit information (EI) about either the first language (L1) or second language (L2) along with task-essential practice can facilitate L2 learning (e.g., Fernández, 2008; McManus, 2022). However, little research has examined L1--L2 contrastive EI with L1/L2 practice. Targeting plural-marking accuracy, the…

Building on Jack Richard's interest in vocabulary, this paper looks at the importance of morphology (how words are formed) in language learning and teaching. It describes why knowledge of morphology is important, and how it affects vocabulary learning. It provides clear guidelines on what word parts to focus on, how much time to spend on word…

The current study reported an empirical investigation that tested the collective and individual effects of morphological awareness and cognate awareness on Japanese word learning among Chinese learners of Japanese. 131 Chinese learners of Japanese participated in this study. They completed morphological awareness measurements (morpheme…

This study investigated the relative ease or difficulty of grammar commonly taught in intermediate (second-year) German at the university level. Previous studies have investigated the ease or difficulty of specific grammar structures, factors that make it difficult to learn L2 grammar, and teachers' and learners' perceptions of difficult grammar.…
