Common Lexical Hedges and their Functions in Medical Research Articles on Oncology: A Comparative study of Thai and Native Writers of English
This study examined and compared the frequencies and functions of common lexical hedges used by non-native (Thai) and native writers in the discussion sections of medical research articles in the area of oncology. A corpus of sixty research articles written in English by both groups were selected and analyzed through descriptive statistics in terms of frequency and a standardized size of 1000 words was employed to provide a basis for comparison. The list of common lexical hedges suggested by Hyland (2005) was used as a guideline. Their frequencies reflect the different preferences of both groups and may also indicate the ability to hedge of Thai writers. Functions of hedges were analyzed through the way they were used and several functions were found. Some pedagogical implications were suggested.
