Functional analysis of Subject and Verb in Theses Abstracts on Applied Linguistics

The purpose of the present study is to analyse abstracts related to Applied Linguistics, and more precisely the discourse functions of grammatical subjects and verbs. The corpus consisted of ۵۰ PhD thesis abstracts written on the subject of Applied Linguistics. All of the abstracts were written from ۲۰۱۰ to ۲۰۱۴. The theses from which the abstracts were extracted are available in the ProQuest database. Based on the model put forth by Swales and Feak (۲۰۰۴), the elements of the abstracts were identified. In accordance with Ebrahimi (۲۰۱۴), frameworks were used to analyse discourse functions, while the realisation of grammatical subjects and verbs was analysed for tense types. The results revealed that the “introducing part of study” and “research-related objects” were the predominant types of grammatical subjects. Indeed, these performed more discourse functions in Applied Linguistics PhD thesis abstracts compared with other grammatical subject types. The results also indicated that simple past tense was predominant in aim, method, and results sections, while the simple present was predominant in the background and conclusion sections.
