No spoken word has a privileged or closer position to the signified (or to meaning) than a written word. If we had that close relation to the signified (which constitutes “full presence” in Derrida’s terminology), then the “play of the sign” (another phrase from Derrida) wouldn't actually occur because we could bypass the signifier of the signifier (that is writing) and achieve closer harmony with the signified (or with meaning/sense).
All we have is play; though it doesn't follow that we believe that all we have is play.
The deconstructionist strategies simply tell us that we have play and that the determinacy of meaning was/is a grand illusion which has played a huge part in Western philosophy.
