This research investigates disciplinary variations using syntactic features in Pakistani academic writing (AW). The corpus of this research is developed from 160 dissertations across four disciplinary divisions and analyzed through AntConc. Results reveal heterogeneous and homogenous use of the said features. Heterogeneity is seen in relation to the frequency of different types of clausal, intermediate, and phrasal features. Regarding the homogeneity, results reveal that the highest and lowest used features were similar across the four disciplinary divisions. That is, clausal coordinating conjunctions and WH complement clauses (highest and lowest used clausal features), nouns and prepositional phrases (highest and lowest used phrasal features), and adverbs and noun+to-clauses (highest and lowest used intermediate features) are observed to remain the same across the four disciplinary divisions. These results conclude that Pakistani AW does not reflect disciplinary variation. The practice is contrary to the expert convention. Therefore, Pakistani academic writers are suggested to appropriately use the syntactic features as per the expert conventions in their disciplines.
