Background: Writing means communication through words whereas academic writing means making careful use of words to communicate ideas to a range of readers and audiences. Therefore, academic writing reflects specificities related to audience, context/discipline and purpose of the use. These specificities result in ample differences in terms of language use.
Purpose: This study investigates disciplinary variation in the use of different syntactic (i.e., clausal, intermediate and phrasal) features in academic writing produced by the Pakistani advanced writers of English as an L2 specializing in different disciplines of arts and humanities, life sciences, physical sciences and social sciences.
Method: For the said purpose, the corpus has been developed from dissertation texts produced by the Pakistani doctoral candidates from 16 academic disciplines of four disciplinary divisions. The analysis has been performed using AntConc Software after tagging with Multidimensional Analysis, and TagAnt Taggers.
Results: The results reveal mixed findings. On the one hand, the results show variation in the use of syntactic features that is observed to be marked by the difference in the frequency of the different types of the said features across disciplines. On the other hand, the results show a similarity in the use of syntactic features that has been evidenced by the finding that the most and least frequently used features are identical across disciplines.
Conclusion: These results suggest both heterogeneity and homogeneity in the use of syntactic features by the Pakistani advanced L2 academic writers. The results of this study have implications for educators, policy makers, and syllabus designers to ensure discipline-specific instruction, and incorporation of the discipline-specific syntactic features into the academic curricula for supporting academic writing development skills in the students particularly at the advanced level of education.
