Différance is a neologism coined by Derrida in his 1968 lecture of the same name, deliberately spelled with an 'a' (instead of the grammatically correct 'e' in 'différence') to make a distinction that is audible only in writing — a performative enactment of the concept itself. Différance combines the French verb 'différer' in its two senses: to differ (to be distinct, to be other) and to defer (to delay, to postpone). Meaning in language is produced through
these two operations simultaneously: signs mean what they mean through their differences from other signs, but the presence of meaning is perpetually deferred — we
never reach a final, self-present meaning but are always referred to further signs. Derrida derives this from Saussure's structural linguistics but radicalizes it: if meaning is constituted by difference,
there can be no originary presence that grounds the system. For poets, différance describes the permanent instability of poetic meaning. Related terms: the trace, supplement, arche-writing, Saussure, logocentrism, iterability.
