Lacan aligns desire with metonymy and the slide of signifiers above the bar, 'indicating that it is the connection between signifier and signifier that permits the lesion in which the signifier installs the lack-of-being in the object relation...in order to invest it with the desire aimed at the very lack it supports'. This produces a situation in which desire is never satisfied, 'being caught in the rails - eternally stretching forth towards the "desire for something else" - of metonymy' Partly for this reason, one's desires can never be identified in a statement along the lines of: 'I desire x, y and z'. Instead, desire is slippery and metonymical.
