This study investigates how postgraduate writers use adjectives in acknowledgements written in English, focusing on their frequency, syntactic characteristics, and distribution across academic degrees and disciplinary domains. The corpus, titled ACK-CO, comprises 256 acknowledgements written by Turkish L1 postgraduate writers in two domains, Humanities and Social Sciences (HSS) and Science, Technology, Engineering, and Mathematics (STEM), and at two degree levels (MA/MS and PhD). All texts were compiled from the Council of Higher Education (CoHE) National Thesis Centre and analysed using R and Sketch Engine. Descriptive analysis showed that acknowledgements in PhD dissertations were longer and contained a higher density of adjectives than those in MA/MS theses. However, chi-square tests comparing the frequency of adjective use across degree levels did not reach statistical significance. The results, nevertheless, suggested a slight tendency toward higher adjective use in the PhD acknowledgements. In contrast, comparison of disciplinary domains revealed a significant difference, with HSS acknowledgements containing more adjectives overall than those in STEM. To gain further insight into how adjectives function within texts, a syntactic analysis revealed a strong preference for an attributive position among the most common adjectives, such as special, valuable, and great. These results, together with the frequency patterns, indicate that disciplinary domain tends to influence adjective use more strongly than degree level. Writers in the soft sciences appear more inclined to use adjectives expressing gratitude and appreciation. The study contributes to corpus-based research on academic register variation by suggesting that adjective use may vary across degree levels and disciplinary domains in postgraduate acknowledgements.
