The study of lexical bundles, among types of text analysis, is gaining importance over the others in the last century. The present study employed a frequency-based analysis approach to the use of lexical bundles. The discussion section of 60 political science articles, with corpora around 253,063 words were investigated in three aspects of structure, form, and function of lexical bundles. The present study selected its data pool out of scholarly articles from qualified journals in the field of political sciences. One part of the data pool was made up of 30 articles written by American native speakers. The second half of the data comprised the 30 articles written by Iranian scholars in political sciences. The findings showed that native and Persian-speaking writers employed the same forms of lexical bundles, and there were significant differences concerning the nativeness and functions. Bearing in mind the findings of the present study, material developers would think of the possibility of the addition of lexical clusters into the materials. It can similarly be valuable for the development of the second language writing strategies, for those who need to write in academic contexts especially political contexts.

Formulaic language and sequence as the core characteristic of real-life language and native-like fluency, has been a subject of inquiry in recent decades. The aim of the present study is to investigate the effects of two extensive reading text types, i.e., adaptive and authentic, on Iranian EFL learners’ development of lexical bundles. To this aim, 20 intermediate EFL learners were chosen to participate in a time-series experiment, in which one class received adaptive texts as their extensive reading project, while the other experienced authentic texts of graded readers. The learners were required to read texts and write summaries, out of which the frequency and percentage of lexical bundles were extracted. The results of frequency and t-tests revealed that learners who benefited from adaptive texts were more successful in lexical bundles progress. While the other group also indicated to have improved in terms of multi-word chunks, the shift was not statistically significant. It is recommended that teachers allocate more class time to explicit and implicit instruction of lexical bundles.

There has been increasing interest in utilizing corpora in linguistic research and pedagogy in recent years. Rhetorical organization of different sections of research articles may appear similar in various disciplines, but close examination may show subtle differences nonetheless. One of the features that has been at the center of attention especially in recent years is the idiomaticity of a discourse which can be examined from the perspective of multi-word units captured by the automatic retrieval of lexical bundles. This study takes a corpus-based approach for the identification of lexical bundles. A corpus of 801,894 words from 790 articles was collected. In order to fulfill the purposes of the present study, ABBYY FineReader 10 professional edition, Total Assistant, Antconc 3.2.3, and WordSmith Tools 5 were used to identify lexical bundles. Then these bundles were classified structurally and functionally based on the presented taxonomies in the literature. The results of the current study indicated that the writers of medical research articles mostly rely on text-oriented bundles in the discussion section of research articles to establish academic discourse.

This paper investigates a special type of recurrent expressions, lexical bundles, defined as a sequence of three or more words that co-occur frequently in a particular register (Biber et al., 1999). Considering the importance of this group of multi-word sequences in academic prose, this study explores the forms and syntactic structures of three- and four-word bundles in English abstracts written by Iranian scholars in three disciplines; business studies, history, and linguistics. Applying a frequency-based approach suggested by Biber et al. (1999), the data were drawn from a corpus consisting of 660 English abstracts of research articles published by various leading academic journals. As regards syntactic structure, the structural characteristics of the lexical bundles were first explored through careful analysis and then classified using a modified version of Biber et al.’s (1999) structural framework. The study also compares the forms, frequencies, and structures of the lexical bundles in the corpus to those found in Hyland’s (2004) research article corpus. This comparison shows that not only are there relatively large differences between the two corpora in the forms and frequencies of bundles employed, but also there are some discrepancies in terms of distribution of the different structural types and tokens.

  This paper investigates the use of ‘lexical bundles’ in two broad corpora of journalistic writing. The aim of this study is to compare the use of lexical bundles in the two domains, one consisted of newspaper articles written in English and published in England and the other one comprised of newspaper articles written in Persian from Iranian publications. For this purpose, the frequency of occurrence and distribution of different functional taxonomies of lexical bundles across the subject matter were investigated. More than 2.5 million words of different English and Persian-produced online newspapers were collected and they were identified by the help of two computer programs, then their functionswere analyzed. Consistent with similar research on lexical bundles, the analysis indicates that most bundles perform a referential function in journalistic register. These findings may be particularly useful to translators and also EFL practitioners, as they seem to give new insights into the development of learner language.

Researchers stated that learning and applying certain set of lexical bundles of native lecturers by non-native lecturers would help students improve their proficiency through incidental vocabulary input. The present study shed light on the lexical bundles in hard science lectures used by Native and Non-native lecturers in international universities with the main purpose of analyzing the structural and functional similarities and differences in their usage. The secondary purpose was to finalize and present a list of explored lexical bundles employed by Native lecturers in these lectures which could be helpful for students and also Non-Native lecturers. The corpus of this study consists of five and a half hours of three different native university lecturers’ lectures and about five and a half hours of three different non-native university lecturers’ lectures who were teaching hard science (nuclear physics and electronic engineering). The data were analyzed using n-gram tool in lextutor.ca website which is a free online software to analyze the lexical bundles of more than two corpora and compare them. Functional and structural analysis gave the following results. Findings showed that lexical richness of both Native and Non-Native lecturers was not good enough to expose students to rich environments to help them improve their English proficiency. In light of structural classification, the results revealed that dependent clause fragments in addition to verb structure phrases were the most widespread and Noun phrase + of-phrase fragments were the least employed structures of the identified lexical bundles in the lectures of Non-Native and Native lecturers. In terms of structural analysis, it was concluded that stance bundles were the most frequent function bundles used by both groups. Therefore, there were both similarities and differences in the structural and functional classifications of lexical bundles in the lectures of native and non-native lecturers.

The study of lexical bundles, known as fixed phrases, chunks, clusters and multi-word expressions, has attracted considerable attention. While there has been much research on lexical bundles across different registers and a number of disciplines, their deployment in some special sections of research articles as the most high-stakes genre has not yet been well explored. Accordingly, the present study aimed at identifying 4-word lexical bundles by analyzing the data obtained from a collection of the abstract and conclusion sections of 1000 English research articles written by L1-persian and L1-English writers in AL and IT , as published between 2015 and 2019. The researchers used Antconc software to analyze the data composed of about 600,000 words; then, the functional analysis was carried out based on Hyland's (2008) framework. Overall, the analysis revealed that AL writers outweighed their IT counterparts in their use of lexical bundles. Also, L1-persian writers used more lexical bundles in the abstract section; despite this, both writers used the same number of bundles in the conclusion section. In addition, both AL and IT writers had a similar use of the three main functional categories; however, there were substantial differences and similarities in regard to these two parts of research articles. The findings of this study can help writing instructors to improve students' academic writing. They can enhance their abilities to better comprehend the role of lexical bundles in different genres and sub-genres.

This study compared the use of lexical bundles in authentic spoken language data with those of two English learning textbooks developed for IELTS preparation courses in Iran. The aim was to see if the language chunks available in the said textbooks were representative of the real-life language for which learners need to prepare. To achieve this aim, firstly, a list of lexical bundles was compiled based on Michigan Corpus of Academic Spoken English (MICASE) and British Academic Spoken English (BASE). Further, the list was used as a reference tool to analyze the language data of two IELTS preparation books published and widely used in Iran. The results highlighted some considerable differences between MICASE and BASE with regard to the use of lexical bundles in terms of their frequency, structure, and function. Moreover, it was revealed that the books under investigation shared only a scarce number of similar lexical bundles with MICASE and BASE as a whole. Therefore, they failed to be representative of the authentic language that people use in real world. Finally, the implications of the study are discussed, and several practical suggestions are made in order to inform teachers, material developers, and syllabus designers of the importance of related corpus linguistic studies.

The present study investigated the use of lexical bundles (LBs) in research articles authored by English L1 and Persian L1 academic writers, with a special focus on the syntactic roles of LBs in a larger context of sentence level. Four-word bundles were retrieved and classified structurally. The use of identified LBs was compared in two writer groups. The syntactic roles and relative complexity of the bundles’ structures were analyzed in relation to Biber, Gray, and Poonpon’s (2011) hypothesized stages of writing development. The results indicated different patterns of reliance on LBs, with Persian writers making greater use of LBs at higher frequency. In addition, Persian academic writers tended to use high frequency bundles differently from native-speaker academic writers. The results of the syntactic analysis of LBs reflected more frequent use of LBs functioning as compressing lexico-grammatical structures in a native English-speaker corpus, which is indicative of a more complex academic register compared to that of a Persian L1 corpus. The pedagogical implications of the findings for the explicit instruction of syntactically complex corpus-driven LBs for discipline-specific genre writing and suggestions for future research are discussed.

The present study sought to find the most frequent lexical bundles, particularly the token of the bundles, in the introduction and discussion sections of Civil Engineering research articles. It also aimed to examine the forms or types of lexical bundles found in the introduction and discussion sections of the articles. To this end, a quantitative analysis was performed on the use of two-to-five-word lexical bundles, followed by a qualitative analysis of their functions and structures based on the structural taxonomy of lexical bundles proposed by Biber, Conrad, and Cortes (2004). AntConc, as a corpus analysis tool, was employed for the extraction of lexical bundles as well as the examination of their types and tokens. Likewise, concordancers and word and keyword frequency generators were used for the analysis of word clusters and lexical bundles.   A total of 790 lexical bundles in the introduction section and 279 lexical bundles in the discussion section were analyzed based on a set of pre-established criteria (e.g., the frequency cut-off of 20 per million words) . The findings revealed that the lexical bundles consisted largely of two-word strings, and the five-word strings were the fewest. Regarding the structural classification of bundles, phrasals were the most frequent ones, whereas clausal on es were the least frequent ones. The study carries important implications, especially for materials developers and course designers who may hopefully benefit from the results in designing EAP materials finely tailored to the linguistic needs of Civil Engineering students.

As building blocks of coherent discourse, lexical bundles, frequent word combinations that commonly occur in different registers, have attracted the attention of researchers in corpus linguistics in the last decade. The importance of these word clusters lies in their often necessary functional contribution to the development of evolving discourse. While most previous studies of bundles have been mainly concerned with variations in the use of these word sequences across different registers (e.g., conversation, classroom teaching, and lectures) and a number of disciplines (e.g., history and biology), postgraduate genres have not been the subject of adequate rigorous analysis. This corpus-based study explored possible differences andor similarities between two students' genres in terms of the variety, structure, and function of lexical bundles. Through two corpora of master theses and doctoral dissertations in one single discipline of applied linguistics, the study showed that not only was there a large intradisciplinary difference between the two genres in the range of bundles employed, but also there were some striking differences in the total frequency and function of these word combinations. Some implications for academic writing instruction have also been discussed.

Research on native vs. non-native formulaic language use in academic texts, despite its wealth in scope and frequency, lacks an inclusive conceptualization of a non-native language learning context. Impressed by such a flawed approach, the bulk (if not all) of studies in the field compared the use of different multi-word strings in the academic discourse of either foreign or second language learners with a native baseline. The current study sought to address the gap, focusing on the structural and functional use of lexical bundles in two culturally parallel corpora developed in two non-native learning context modes: English as a foreign (EFL) and second (ESL) language. To this end, research reports written by Iranian Applied Linguistics MA and Ph.D. learners studying in different universities in Iran and English-speaking provinces of Canada were compared by a structurally similar native corpus, running cross-tabulation, Chi-square, and residual analysis analyses. The results revealed a significant association between language learning context and lexical bundle use on a functional level. The contextual variations yielded significantly different patterns of use concerning several micro-functions underlying text-oriented and research-oriented functions. Compared to functional differences, the between-corpus structural differences were inconspicuous, specifically concerning micro-structures constituting noun, prepositional, and verb phrase-related bundles. The study embraced the notion that EFL writers need to have immense exposure and enhanced language input available in ESL and native learning contexts to foster a native-like formulaic language.

Lexical bundles are recurrent multi-word sequences that play a crucial role in academic discourse. This article presents an analysis of lexical bundles in book reviews across the disciplines of human and natural sciences. Drawing from a corpus of 737 book reviews, the study investigates the functional roles and structural patterns of these recurrent linguistic units. The research aims to bridge a gap in the literature by exploring how lexical bundles vary across disciplines. Employing a quantitative-qualitative approach, the study first quantitatively identifies the most common 4-word lexical bundles and compares their distribution between the two disciplines. The researchers then qualitatively analyzed the context in which these bundles are used, observing that they often serve to refer to or evaluate the structure, content, audience, or scope of the book under review. Findings reveal that while both human and natural sciences book reviews share some lexical bundles, they exhibit variations in their distribution, structures, and functions. Notably, natural sciences book reviews employ a greater frequency of lexical bundles signaling an evaluative context, particularly contexts related to the assessment of a book. The study also uncovers differences in the structural preferences of lexical bundles between the two disciplines. This research contributes to a deeper understanding of the genre-specific utilization of lexical bundles and underscores their role in conveying evaluative meaning in scholarly discourse. Furthermore, the study suggests avenues for further exploration, providing a foundation for future investigations into the intricate interplay between linguistic features and disciplinary preferences.

As one of the most prominent components of native-like language use, lexical bundles play a crucial role in academic texts. Considering the amount of written language produced by writers, this study explored lexical bundles in non-native and native academic reports. To that end, 100 sample reports of non-native and native writers taken from the Michigan Corpus of Upper-level Student Papers (MICUSP) were selected and analyzed to find non-native and native writers’ use of lexical bundles regarding frequency, structure, and function. Results indicated that native writers generally used a more extensive variety of lexical bundles in their reports. Regarding the structure of bundles, both non-native and native writers tended to employ more noun phrases with of-phrase fragments. In terms of the functions of bundles, both groups of writers tended to use more research-oriented bundles, followed by text-oriented and participant-oriented bundles, respectively. Findings highlight the value of fixed expressions in producing coherent academic texts by proficient writers, hence their importance in materials design and second language instruction.
