Taiwanese (台語), also known as Tâi-gí, is the most widely spoken native language in Taiwan. During both the Japanese colonial period and subsequent martial law era (1949-1987), Taiwanese and other indigenous languages faced severe repression. While democratization has restored the freedom to speak Taiwanese openly, new challenges have emerged. As fewer young people speak the language, the question looms: how can this once-flourishing mother tongue survive in an era of globalization?"
