This thesis is based on the concept of investing in the Italian language and identity of Erasmus students in Turin. The aim of this research is to determine investment of the mentioned students in the Italian language and to interpret how and which sociological aspects affect the learning and use of a second language. The mayor part of the research is based on audio recordings of semi-structured interviews with five Erasmus students, while the rest was conducted of the written google form questionnaires. The findings of the study indicated the factors influencing the investment of Erasmus students in Italy and the power relations between native and non-native speakers, when there is potential for asymmetries of power to shape how interaction occurs. The answers of the students has showed that all the interviewed students have positive attitudes towards the Italian language as well as their willingness to communicate with native italian speakers, regardless of their language level. Although they did not face discrimination of any kind, the respondents indicated that sometimes they feel the insecurity and fear of making mistakes when talking to native speakers who have the power to evaluate their linguistic performance and draw inferences from it. Furthermore, the students agree that the languages they speak can play an important role in expressing their cultural and linguistic identity and that learning two or more languages has helped them understand the cultural complexity of the country they are staying in. The research has also showed that investing in the second language means engagement and exposure to that language through content and interaction with the society that surrounds them.
