It is a practise employed by multilinguals in both oral and written conversations. Different multilinguals will have different switching patterns. These patterns can vary depending on the speaker’s language proficiency, community norms, the typology of their languages, and the cultural or political relations these languages might have with one another, among many other reasons. Code switching between Spanish and English and Spanish and French has been the subject of various studies. Although trilingual research is rare (e.g. Parafita Couto et al., 2023; Valdés Kroff et al., 2023), there has also been some research on the connection between Spanish, French and English, but most of this work is based in the French-speaking provinces of Canada (e.g. COLEM, 2023; Pato, 2019, 2022). This paper aims to study the code-switching patterns among a set of trilingual siblings living in Geneva who have Colombian heritage and attend a British school in the city. The participants recorded themselves for up to 30 minutes having casual conversations following a prompt in three separate occasions. The switches were identified alongside general information about the corpus, such as how many languages were present in each clause, the clauses’ matrix language, the general use of each language in the corpus, among others. This paper focuses on intraclausal switching. We followed Deuchar et al. (2007)’s methodology which categorises each intraclausal switch into insertion, alteration, or congruent lexicalisation according to the code switching pattern it most aligned with following Muysken’s typology of bilingual speech patterns (2000).Because English, Spanish and French are typologically similar, combined with the fact our participants are fluent in all three languages, and due to the culturally open context of Geneva, we expected alternation to be the dominant switch pattern in the recorded conversations. Having said this, since the participants go to a British school where their education is mainly in English, and because the Colombian community in Geneva is not as big as other bilingual communities around the world, a dominant insertional pattern was also a possibility. The corpus was composed of mainly unilingual clauses with 7.8% of the first recording being bilingual clauses, 19.6% of the second recording, and 8.95% of the third. Only three clauses in the entire corpus were trilingual out of 1215. Once we had analysed the entirety of the conversations, the dominant pattern was indeed overwhelmingly insertion with 77.55% of the switches in the corpus presenting this pattern. Congruent lexicalisation was present in 11.56% of the switches and alternation in the other 10.88%. Although these results do not necessarily align with our expectations of codeswitching in Switzerland, we believe our participants’ specific background, namely the fact that language separation is encouraged in the different spheres of their lives, could explain the prevalence of insertion over alternation in our case study. We hope our research will contribute to bigger corpus studies of trilingual codeswitching patterns in different communities.Show less
