This thesis is a course of study on the work of Sándor Ferenczi, having as reading tool the conception of language game formulated by Wittgenstein, and the ethical dimension presents itself as guiding element for the proposed questions. The language games that permeate Ferenczian formulations, both in the theoretical and clinical fields, allow us to capture the transformations occurred over time. We perceive how Ferenczi s primordial focus on contributing to the classical technique gradually changed and opened space for a more experimental aspect, resulting in the creation of a particular and unique vocabulary by enabling innovative perceptions on subjectivity.
