The letter refers to the material substrate, identical to the printed character, that serves as the vehicle for spoken or written language. It represents the two sides of the signifier (metaphor and metonymy) in the creation of meaning and in the production of dreams, where the letter designates one of the terms of the rebus. As the localized structure of the signifier, the letter's nature is real, exclusive of sense or meaning. Its function is symbolic to the extent that its absence determines the automatism of repetition. The letter constitutes the unconscious to the extent that it is organized as a literal heterogeneous set.
