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.…

Although several studies have focused on novel word learning and lexicalization in (presumably) monolingual speakers, less is known about how bilinguals add novel words to their mental lexicon. In this study we trained 33 English-French bilinguals on novel word-forms that were neighbors to English words with no existing neighbors. The number of…

This study set out to investigate the relationship between L2 vocabulary knowledge (VK) and second-language (L2) reading/listening comprehension. More than 100 individual studies were included in this meta-analysis, which generated 276 effect sizes from a sample of almost 21,000 learners. The current meta-analysis had several major findings.…

This study presents a list of 2022 Bulgarian-Turkish cognate words that can be used to facilitate vocabulary acquisition and cross-linguistic awareness. The list was created manually through a multi-step process that involved scanning the database of an online dictionary to identify Bulgarian words that had the same or similar forms in Turkish.…

Research suggests new foreign language (FL) words are learned more easily if their phonology follows the phonotactic rules of the native language. Very little is known, however, about the impact of orthography on FL learning. This study investigated the cognitive mechanisms supporting the learning of words with familiar and unfamiliar…

This meta-analysis synthesized the effects of the English medium instruction and content and language integrated learning (EMI-CLIL) approach on secondary-level students' English learning. The dataset included 44 samples (N = 7,434) from 38 primary studies. The results revealed EMI-CLIL's overall effectiveness for the development of English…

The relationship between first and second language in early vocabulary acquisition in bilingual children is still debated in the literature. This study compared the expressive vocabulary of 39 equivalently low-SES two-year-old bilingual children from immigrant families with different heritage languages (Romanian vs. Nigerian English) and the same…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

Lexical inference through reading is considered an important method for vocabulary building; however, empirical research has not consistently offered strong evidence of the application of lexical inference in second language vocabulary learning. A recently burgeoning line of research focuses on second language (L2) lexical inference of compounds…

Although English and German are both Germanic languages, due to various historical changes, many of their cognates are no longer easily recognizable. This study examined whether knowledge of language history can be beneficial to learners when learning English-German cognates. Thirty-five English-speaking second language (L2) learners of…

Previous research indicates that infant-directed speech (IDS) is usually slower than adult-directed speech (ADS) and mothers prefer placing a focused word in isolation or utterance-final position in (English) IDS, which may benefit word learning. This study investigated the speaking rate and word position of IDS in two typologically-distinct…

We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of…

Bilingual children with a limited command of the second language (L2) often yield unsatisfactory results in L2-based non-word repetition tasks (NWRT) for the assessment of working memory. In this study, monolinguals (MO) and bilinguals (BI) of preschool age acquiring German were compared in regard to their performance on German-based NWRT to…

This study investigated the influence of phonological word representations from both first language (L1) and second language (L2) on third language (L3) lexical learning in L1-dominant Spanish-English bilinguals. More specifically, we used event-related potentials (ERPs) to determine whether L1 Spanish and L2 English phonology modulates…

This paper applies the theories of linguistic distance and translanguaging to analyse the pedagogy of teaching vocabulary and grammar in English to Malay-English bilinguals who are struggling to read in English. More specifically the paper explores how the teacher tried to create cross-linguistic transfer and how the students display…
