This ethnographic study aims to analyze the possible constructed personalities of Language School students of a public university in Bucaramanga who are learning Portuguese as a third language. Semi-structured interviews and observations were used to gather the information needed. From them, we concluded that students do not develop or create a new full personality but as they have more exposure and contact with the language, they decide to adopt certain features associated with Brazilian culture. Since this was a small-scale investigation due to the low number of students who are learning Portuguese as L3, further research should focus on studying larger samples and longer-duration observations to try to identify the Big Five personality traits.
