Purpose: The overall aim of the chapter is to explore how preschoolers with different language backgrounds accomplish everyday interaction at a Swedish preschool, where the lingua franca (common language) is Swedish. More specifically, it aims to analyze how the target children, despite their limited language resources in Swedish, use their existing communicative resources to make friends and achieve intersubjectivity in front of two alphabet charts illustrating the Arabic and Latin alphabets, respectively. Methodology/approach: The data are drawn from a single play episode between three boys and a girl, aged four years. Their interaction was video-recorded, and the analytical framework of the study is influenced by ethnomethodological work on social action focusing particularly on participants' methodical ways of accomplishing and making sense of social activities. Findings: The analyses show that the children's trajectory of achieving intersubjectivity was partly bothersome as their interpretation of the alphabet charts diverged, due to their different language knowledge and earlier experiences. Hence, to attain joint understanding and intersubjectivity, they used a range of communicative resources: besides speaking Swedish they used word mixing, attention-getters ("look" and "check it out"), and nonverbal moves such as pointing, gesturing, intone, and screaming. It is notable that, despite some problems in understanding, their desire to make friends and have fun together seemed to compensate for their joint failure to always understand each other. Practical implications: Detailed analyses and observations of how children with diverse language backgrounds use their communicative resources to achieve intersubjectivity and make friends can be useful for preschool teachers' understanding of how they can further support the children's socialization and capturing of the majority language - here Swedish. Originality/value: The present chapter contributes to a wider understanding of how second-language learning is a complex trajectory edged with both setbacks and successes, especially when all the children interacting have diverse language backgrounds and experiences. However, the analysis highlights how, in their endeavor to make friends, the children find ways to solve problems in situ in their own way, and enjoy each other's company despite the fragility of the play and their language shortcomings.
