A funded X-Student Research Group (summer semester 2026) under the Berlin University Alliance Student Research Opportunities Program (StuROPx), led by Olga Olina (Humboldt-Universität zu Berlin, Deutsche Sprache und Linguistik). The group investigates grassroots initiatives in Berlin's heritage language communities and the forms of institutional support currently missing or difficult to access, aiming to develop concrete ideas for a proposed 'Heritage Speaker Status'. Through interviews with Berlin-based NGOs supporting linguistic diversity and with minority-language speakers, complemented by archival research, it explores (i) heritage languages and support structures in Berlin and (ii) minority languages and language policy in Germany and beyond. Research is linked to outreach via two Berlin events (Karneval der Kulturen and 48 Stunden Neukölln) to exchange directly with communities and map initiatives across the city.
