This paper explores the psychodynamics of analytic work conducted between a French patient and an American analyst who are both bilingual in French and English. The depth of the patient's early traumatic relational history is initially bound and cloistered in French, her mother tongue. The author argues that through the symbolization of a series of initially dissociated enactments a transitional space is created in the treatment, facilitating the integration of the patient's (and analyst's) early French-speaking selves. Language is considered as a container for both dissociative and associative forms of multiplicity, as it serves to mediate an external and internal intersubjective expansion both between and within patient and analyst.
