Using varied offline and online contexts, this paper points out that youth linguistic diversity in modern Mongolia is better grasped from the view of ‘the ordinariness of linguascapes’. The concept of ‘linguascapes’ is significant in capturing the rising intricacy of youth mixed language practices fundamentally generated by the amalgamation of transnational linguistic resources that are intersecting with other social landscapes. However, these youth linguascapes in Mongolia are neither new nor unconventional linguistic productions as mainly imagined in the local language ideology. Instead, youth linguascapes in Mongolia should be grasped as part of young people's everyday, mundane and ordinary linguistic practices. Thus, it is important for language educators and language policy-makers in Mongolia to reconsider youth linguistic diversity in globalisation through the eyes of sameness of differences or the ordinariness of the diversity.
