This article presents a review of speech patterns and structures that clients may use to communicate information about their difficulties to a counseling psychologist. The material presented in the article will help practicing psychologists focus on what and how the client speaks during the consultation, and use this information provided by the client to promote the therapeutic process. The article examines different authors’ views of a client’s speech. E. Berne, the founder of Transactional analysis, invites to identify the client’s script process through their speech, as well as recognize different levels of information received from the client (overt and covert). S. Freud describes the “breakthrough” of repressed impulses through the slips of the tongue.The article outlines various word groups and expressions that may be heard from the client in the dialogue: overgeneralizations – words that help individuals adapt by generalizing objects according to certain features; evaluative words, used to express the norms of various social groups; slips of the tongue and misspellings, through which one can hear “unconscious impulses repressed by the client”; obscene words, through which a person comes into contact with their Shadow; and aggressive verbs together with methods of confronting them.
