Patients' use of language in the analytic setting can undergo extreme and sometimes surprising fluctuations. Seemingly articulate and engaging patients retreat to the concrete in their use of words, disconnecting verbal expression from one's internal experience. Are these fluctuations indications of limitations in the patient's capacity to put experience into language, or are they indications of the emergence of otherwise unacknowledged aspects of self into the treatment arena? Shifts in the use of language (both patient's and therapist's) can be opportunities to question the work of the analysis. Whether one uses these moments to expand the boundaries of the analytic technique or to expand the boundaries of the analytic relationship—or both—is the question posed in this commentary.
