This article examines how Russian speakers in Ireland delimit and describe (their/the) Russian language in relation to representations of standard Russian. It is based on analysis of discussions conducted between speakers of Russian living in Ireland, facilitated by the Our Languages (2008-2011) research project, investigating multilingualism and sociolinguistic dispositions amid Ireland's Russian-speaking population. Three metalinguistic orientations are foregrounded: (1) participants affirm the naturally and normatively discrete identity of 'the' Russian language; (2) despite this unitary identity, participants distinguish between registers and levels of relative purity in Russian; (3) participants relate generalised linguistic form to a concept of community. The interplay of these orientations -- toward an essentially unitary and unifying Russian language, away from 'improper' forms of that language, and into reflection on collective identity -- reveals a model culture of standard language within the polyglossic context of Irish society, combining the routinely claimed characteristics of generality and authenticity. The article interprets the contradictory dynamic between these characteristics in relation to a Bakhtinian concept of "monolingualism" and a critical conceptualisation of "language community." Participants configure Russian as one among 'our languages' through the iterative negotiation of a tension between ideological monolingualism and actual heteroglossia.
