Primary and Secondary Repression
He later distinguished between primal repression (a "mythical" forgetting of something that was never conscious to begin with, an originary "psychical act" by which the unconscious is first constituted) and secondary repression (concrete acts of repression whereby some idea or perception that was once conscious is expelled from the conscious).
Since repression does not destroy the ideas or memories that are its target, but merely confines them to the unconscious, the repressed material is always liable to return in a distorted form, in symptoms, dreams, slips of the tongue, etc. (the return of the repressed).
What is it that is repressed? At one point Lacan speaks of the signified as the object of repression, but he soon abandons this view and argues instead that it is always a signifier that is repressed, never a signified. This latter view seems to correspond more closely to Freud's view that what is repressed is not the "affect" (which can only be displaced or transformed) but the "ideational representative" of the drive.
Primary and Secondary
Primal repression (German: Urverdrängung) is the alienation of desire when need is articulated in demand. It is also the unconscious signifying chain. Primary repression is the repression of the first signifier.
Lacan does not see primary repression as a specific psychical act, localizable in time, but as a structural feature of language itself - namely, its necessary incompleteness, the impossibility of ever saying "the truth about truth."
Secondary repression (German" Verdrängung) is a specific psychical act by which a signifier is elided from the signifying chain. Secondary repression is structured like a metaphor, and always involves 'the return of the repressed', whereby the repressed signifier reappears under the guise of the various formations of the unconscious (i.e. symptoms, dreams, parapraxes, jokes, etc.). In secondary repression, repression and the return of the repressed "are the same thing."
