In psychoanalytical practice important, but less studied, transformative functions are performed by verbal comments which do not correspond to the classic model of mutative interpretations proposed by Strachey. The Authors describe some characteristics of such clinical situations, without coming into the better known categories of variations in technique. Such enunciations seem not to have a “strong”, (already clearly defined) meaning in the mind of the analyst, but contain rather a “weak” semantic potential, which can only develop with the active cooperation of the patient. In the light of these experiences, the Authors reconsider the general nature of psychoanalytical interpretation and emphasize the intersubjective and dialogical nature of the interpretive work carried out in analysis.
