Abstract
The article focuses on the study of borderline cases of insertion of addresses to the other or words reported within a genre with shifted enunciation: the novel by letters in the eighteenth century. Self-citation, free indirect speech, interpreted reported speeches, and dysfunctions in verbal interaction are all observation posts for the enunciative but also heuristic strategies writers conceive to relieve the microcosm they create. The choice of the letter creates a tension between the two levels of enunciation. We will see how the selection of the different types of reported speeches informs the specific scenography of each examined work and proposes a renegotiation of the three enunciative postures.
