In this study, we investigate the three-dot sign as a discourse marker (DM) with textual, subjective and intersubjective discourse functions. As a graphical marker that is used across languages, the three-dot sign is especially suitable for comparative studies and dynamics in language contact. Our corpus study targeting instant messages of different languages (English, German, Greek, Russian, Turkish) and speaker groups (monolinguals and bilingual heritage speakers) suggests that graphical DMs are prone to cross-linguistic influence. This depends on the specific contact situation and does not seem to be a general effect of bilingualism. The societal status of a language might further influence the use of such markers in digital informal writing. Language-specific developments that relate to emerging functions indicate that functional versatility promotes frequent use of (graphical) DMs.

We investigate emoji as graphic discourse markers in German WhatsApp® messages. As comparably novel devices in the rapidly evolving domain of digital messenging, emoji provide an interesting example to observe change in progress. We present a corpus study and an experimental study. Main results are (i) an overall salience of subjective and intersubjective discourse meanings for emoji, with (ii) a general advantage for the former, especially for emoji that iconically include more active elements, while (iii) dominance relations can be modulated by left- vs. right-peripheral positions in favor of subjective vs. intersubjective meanings, respectively. By approaching emoji as discourse markers, the studies contribute to our understanding of their pragmatic contribution and provide novel evidence on positional-functional associations for pragmatic markers.

This study investigates the variation of the polyfunctional linguistic item also across registers and language contact settings. I present findings from a corpus study using the corpus of the Research Unit Emerging Grammars, RUEG for short (Wiese et al., 2019), which provides comparable, register-differentiated data of bilingual and monolingual speakers of German in Germany and bilingual heritage speakers of German in the US. The data suggest that functional variation of a specific lexical item reflects the use of functional features in specific communicative situations. The data further indicate an impact of the societal status that a language occupies in the larger society (majority vs. heritage language) on the distribution of such functions.
