The development of lexical expressions such as VP adverbs, matrix clauses and prepositional phrases into discourse markers and connectives expressing coherence relations has been well explored in the grammaticalization literature, under a broad view of grammaticalization, but there has been less emphasis on how the discourse information structuring functions of markers evolve during these developments. This paper investigates the relationship between discourse coherence marking and information structure by examining two developing discourse connectives: it suggests that the grammaticalization of a lexeme in its construction into a discourse marker may involve acquiring or strengthening discourse-level information structuring functions-indicating relative informational salience-and that (further) grammaticalization of markers may be at least partly directed by information structure.
