Hedging is a type of interpersonal metadiscourse strategy. Hedging strategies not only show writer's degree of confidence in the truth of a proposition but also reveal writer's attitude to the reader. Compared to other parts of theses, abstract writing has received less attention and the focus has largely been on length, summary and keywords. Abstracts are important components of academic studies because readers decide to continue or stop reading depending on what they get from the content of the abstracts. Therefore, the present study tries to reveal Turkish MA students' use of lexical hedging strategies in MA theses abstracts from the fields of ELT, Chemistry, Biology and International Relations and Political Science. The aim is to analyze if there is any subject specific variation in the use of hedging strategies with respect to frequency counts on lexical bases.
