The paper investigates ways of closing a sequence and an entire interaction in Russian. It analyses linguistic forms used for this purpose and their functions in a radio phone-in programme and compares them with those found in Russian ordinary telephone conversations. This study is based on the methodology of conversation analysis. Firstly, it discusses a broad range of closings in the Russian phone-in and everyday telephone interactions. Thereafter, it focuses on a specific linguistic form ‘ladna’. The analysis shows that although radio phone-in programmes share some characteristics with ordinary talk, differences exist in the organization of the conversation, linguistic forms deployed and functions they perform. Furthermore, the Russian form ‘ladna’ turns out to be language-specific with regard to its functions. Consequently, the research confirms the existence of language peculiarities in sequence organization.
