Stance bundles serve to express recognition of certainty or the writer/interlocutor's attitudes. According to Fang Park, (2020) even though numerous research studies have been focused on lexical bundles and stance markers in different disciplines (Hyland 2008a; Wachidah, W. D. N. A., Fitriati, Widhiyanto 2020), a few studies have been done in Engineering (Rezoug Vincent, 2018). This study expands the research domain of previous studies of lexical bundles by examining the variety and frequency of stance through lexical bundles in three academic genres of engineering vs. applied linguistics. For the analysis of four-word lexical bundles, lexical bundles have defined in the textbooks, research articles and theses of engineering and applied linguistics and the number of texts within which each bundle uses by Antconc3.5.8 in order to compare similarities and differences in the use of lexical bundles in engineering and applied linguistics, as well as, find out what are the most frequent lexical bundles in the engineering and applied linguistics which show the stance of the writer. As a result, engineering writers write more based on the facts and not on their personal ideas and thoughts; however, applied linguistics' writers use more personal bundles, so we can say that maybe they write more based on their personal ideas and thoughts and not the facts. The findings of such a study would be of great help to language teachers to create language teaching materials that unify awareness of the pragmatic use of stance bundles in particular disciplines.
