In the Case of Theme: Topic Identifiers in English and Norwegian Academic Texts

Abstract

Abstract This paper investigates the use of clause-initial constituents prefaced by topic-identifying expressions such as in terms of, in the case of and their Norwegian counterparts. The focus is on the nature, frequency and discourse functions of these in a corpus of published academic writing in English and Norwegian and across three disciplines. Such expressions are rather infrequent overall, but medicine uses them the least and linguistics the most in both languages. The functions of the construction can be compared either to those of left dislocation or to other types of clause-initial adverbials depending on the degree of coreference between the theme and some element in the rheme. The pattern with coreference is more common in Norwegian than in English. Generally, topic identifiers are used for announcing explicitly a theme that represents a topic shift or a contrast with the preceding discourse. The study contributes to contrastive pragmatics through its focus on the discourse-pragmatic functions of the expressions under study and the cross-linguistic comparison of this type of information structuring device across different disciplines of academic writing.
