This study aims to examine the differences of language registers between TV news and newspaper, based on Halliday(1978)'s register concept. Register can be defined as a variable related to a situational context of language use. Halliday(1978) argued that our ways of using languages depended on the details of context of situation, such as what a text is, who joined text production and which role language plays in text and that these referred to field, tenor and mode respectively.
To sum up, TV news and newspaper showed differences in 'tenor' and 'mode'. Expecially, 'modality' in tenor and 'conjunctive ending(particularly, '-neunde') and 'NP-sentence' in mode were remarkably different. Modality is a linguistic device used when a text producer evaluates the validity of proposition and etc. The difference of this modality comes from intimacy in a position of each press towards a reporting target. In relation to modality expressions, KBS that was not free from criticism about the government at that time mostly used 'probably', while Chosunilbo that was critical towards the government mostly used 'certainly'. This relational difference is also discovered in the use of '-giro ha-' or '-neun/eul gyehoeg/bangchim/yejeong/jeonmang'. In terms of modes, conjunctive endings were more frequently used by KBS than Chosunilbo. In particular, the prominent use of '-neunde' in KBS was regarded as a case to show the differences between spoken and written languages. In addition, 'NP-sentence' was not found in Chosunilbo, whereas this was used much by KBS. This means NP-sentence is a part to show differences in mode among situational contexts that are found in formal, planned and non-mutual spoken languages, as discussed in Choi(2019)'s research.
