One Mind, Many Languages: Czech as an Additional Language in Plurilingual Repertoires

Abstract Plurilingualism goes beyond the mere ability to use multiple languages; it emphasizes the interconnected nature of languages within an individual's linguistic competence. In line with the European language policy, university students are becoming users of several languages, and international university students in Czech universities often learn Czech as their fourth language or beyond (L4+). Understanding how their linguistic competencies interact can impact their language acquisition experience. Learners may perceive interactions among the languages within their linguistic repertoire. The concept of Perceived Positive Language Interaction (PPLI, Thompson, 2016) pertains to the perception that languages previously studied are interrelated in a positive way, ultimately enhancing a plurilingual's ability to acquire additional languages. This study explores the relationships between Czech as an additional language and the learners' prior languages. The research aims to answer three main questions: Do learners of Czech as L4+ perceive positive interactions among their learned languages? In what areas do these interactions manifest? How does Czech relate to their other languages? The study was conducted at a Czech university that provides optional introductory Czech courses (A1/A2), primarily to students in the Erasmus+ program. Fifty-four international students filled in an open-ended online questionnaire over two consecutive semesters. The analysis revealed that while students perceived positive interactions among some of the languages they had learned, especially within language families, interactions across typologically different languages occurred, particularly between Czech and German. The participants' mother tongue also emerged as a significant factor. While language instruction often follows a monolingual approach, where the target language is the primary mode of classroom interaction (Woll, 2020), learners may significantly benefit from their previous language learning experiences when learning an additional language. Despite the relatively limited research sample, this study suggests the didactic potential of positive language interaction in language teaching and learning and highlights further research opportunities.
