Private language is that which should remain private and frequently does not. In psychoanalytic psychiatry technical jargon is sometimes used with the patient. Two examples are given of the use of either inexact interpretation or interpretation which is really an indictment of the patient, both reflecting the anger and frustration of the therapist. Devereux, Sterba, and Orr are quoted in a plea to limit the use of our scientific vocabulary to matters of scientific communication and not as technical jargon in therapy, community, or social encounters.
