Drawing on the treatment of an adolescent, the author describes the long and tortuous path leading to the work of mourning childhood objects, thereby enabling the patient to acquire his own psychic space and an impersonal superego. At the beginning of the treatment, the patient uses his mother’s language in the session, rather than his father’s language. This choice reflects the passionate bond with the primary object. The language of origins allows the patient to unravel the thread of his childhood history, punctuated by past bereavements and separations. Step by step, thanks to the analyst’s discreet interventions and the attention paid to affective movements, childhood memories are rediscovered and new associative capacities emerge. The father figure and his language are then cathected. The language of analysis and of the analyst gradually become a third language, a language that separates, a border enabling the patient to find a personal space, a new freedom, and a real bonus of pleasure.
