This paper examines code-switching – the dynamic process of modifying self-presentation or expression in response to environmental and social contexts – within the subjectivity of individuals with marginalized identities. Emphasizing its relational, contextual, and dynamic functions, this discussion explores the psychological and interpersonal dimensions of code-switching. A clinical example will illustrate its functions and possibilities in the psychoanalytic encounter, highlighting implications for clinical practice and training. Drawing from diverse perspectives, including race, gender, sexuality, and language, this paper advances psychoanalytic understanding of code-switching as a nuanced and overdetermined phenomenon.
