The purpose of this article is to synthesize and analyse the most frequently occurring, widely dispersed and pedagogically useful lexical bundles in mathematical texts. Drawing on a five-million-word corpus of graduate-level textbooks, a total of 65 academic sequences meeting a predefined set of length, frequency and distribution criteria are…

The researchers investigated the usage of appropriate academic English vocabulary in research papers authored by English major students, publications in Thai national journals, and international journals. In total, 708 papers published between 2016 and 2018 were analyzed, consisting of 300 international research papers, 300 national research…

Emotiology is a growing area of interdisciplinary research and academic discourse which focuses on the linguistic manifestation of emotions. This study employs psycholinguistic methodologies to examine the rationale behind word selection in emotional communication, integrating linguacultural, psycholinguistic, structural, and comparative analyses.…

Modifying and hedging one's claims appropriately is an important characteristic of academic writing. This study focuses on the three main English modal verbs used to express "epistemic possibility" to avoid making strong statements, viz., "may", "might", and "could". The purpose of this corpus-based study is…

Academic vocabulary is regarded as an important vocabulary set for students at the tertiary to master's levels. Besides academic vocabulary, field-specific vocabulary is another important set that students in different fields of study should be required to explore. The physical education and sports science English word list was created to assist…

This study explored words in materials science research articles using New Academic Word List (NAWL) and New General Service List (NGSL) created by Browne at al. (2013) as reference lists. The objectives of this research were to explore the frequency and coverage of the NAWL and the NGSL in materials science research articles and identify…

In this reflective paper, we review the currently-used word classification system proposed by linguist Paul Nation (2013, 2015) and the position of the academic vocabulary in this system. Different lexical layers in this system are explained as well as the underlying assumptions. Then, taking a critical position, we raise a number of criticisms…

General academic words are those which are typically learned through exposure to school texts and occur across disciplines. We examined academic vocabulary assessment data from a group of English-speaking middle school students (N = 1,747). We tested how word frequency, complexity, proximity, polysemy, and diversity related to students' knowledge…

Corpus-based studies of lexical bundles have opened new avenues for language teaching research. The fact that naturally occurring language consists of patterns of lexical repetition and multi-word units has given rise to the question of chunkiness in learner language. This study was designed to examine lexical bundles and their functions in a…

In recent years, there has been a growing trend of using informal styles in academic writing, including research articles. To examine the degree of formality in students' writing, this corpus-based study aimed to analyze the formal linguistic features in the academic writing assignments of English-major students at a Thai university. The learner…

As a key component of fluent linguistic production, multi-word sequences called lexical bundles are considered an important distinguishing feature of discourse in different registers, genres, and disciplines. They are also an important aspect of empirically correct and proficient language use in a corpus of natural language because they enable…

In this commentary, we begin with the discussion on a brief history of academic wordlists. Adopting a comparative perspective, then, the merits and demerits of the Academic Word List (AWL) (Coxhead, 2000) and its competing counterpart the Academic Vocabulary List (AVL) (Gardner & Davies, 2014) are presented. We also explore whether the AWL can…

When learning high- and mid-frequency words, approximately 5,000 words might be inadequate for learners to survive in a career as a tourist guide. This paper aims to construct technical word lists for Thai tourist guides to serve as supplementary learning materials. Different word lists need different criteria for their construction. Three main…

Research into vocabulary knowledge often differentiates between breadth (how many words a person knows) and depth (how well the words are known). Both theoretical categories are essential for understanding language learners' lexical development, but how the different aspects of vocabulary knowledge interconnect has not received the same attention…
