Evidential adverbs in German

Abstract

Abstract This article addresses the semantic and morphosyntactic development of the German evidential adverbs offensichtlich, offenbar, anscheinend , and scheinbar ‘obviously’/‘apparently’/‘seemingly’ and their meaning contribution in present-day German. It will be argued that these expressions, most of which are historically derived from adjectives, innovated separate lexical entries as sentence adverbs in New High German resulting from a morphosyntactic reanalysis of an ambiguous surface structure. This reanalysis was accompanied by a profound semantic change, as a result of which the expressions acquired a wide-scope reading of the type ‘there is (clear) evidence that p’. The diachronic results are corroborated by experimental data from Present-Day German that show that these evidential sentence adverbs are underspecified with respect to evidence type (inference and report). The diachronic and synchronic findings are furthermore discussed in the light of grammaticalization and subjectification theory.
