this study, an attempt is made to explore hedging forms and functions to identify the similarities and differences between the English weather forecasts and Vietnamese ones in terms of hedging forms and pragmatic functions The data for analysis was taken from 60 weather forecasts in English and in Vietnamese with about 619 samples of hedges in total In order to achieve the aims and objectives, a contrastive analysis of the data was conducted, following both qualitative and quantitative approaches lu Taking the classification of hedges of Varttala’s (2001) as the theoretical an n va framework, the study targets at spotting the hedging forms The research tn to results indicated that the employment of the hedging forms in the English and Vietnamese data shared many similarities The study registered the gh p ie occurrence of two types of hedges, namely lexical hedges and phrasal hedges, w with lexical hedges taking the lead in the English data and phrasal hedges oa nl being the most prominent category of hedges in the Vietnamese data Besides, d the outcomes dealt with functions of hedges by using Grice’s (1975) maxims lu an as the framework Quality hedges emerged as the most prominent categories u nf va in both sources of the data The remaining categories, namely, quantity ll hedges, manner hedges, relevance hedges and mixed hedges were distributed m oi unevenly in the

on Saturday ll oi morning m night, but could still fall to -1C in some parts of England during the early hours of Monday z at nh She said: “To sum up the week ahead, it starts mainly dry, away from Scotland Certainly cold at first, as we head towards the end of the week, we will see the return of something z wetter and windier @ “So the dominating feature through the first half of the week is this area of high pressure gm Notice that fronts are just fringing Scotland, in a much wetter and windier day here on m co l Monday “The rain, initially on the western side of Scotland tracking its

battered by a huge Atlantic system packing heavy rain and strong winds According to the BBC Weather long-range forecast lu for Saturday 30 November to Sunday December warns: “Through the middle to
