Signifiantisation

Signifiantisation (rendered in English as "turning into signifiers" or "making into signifiers") names a peculiar effort — compelled and ultimately exhausting — by which a subject attempts to convert raw, unassimilable experience into the currency of the signifying chain. In the context where Lacan coins the term (Seminar VI, p.401), the concept describes the psychic labour visible in symptomatic fatigue: the subject strains to impose signifying form onto something that resists symbolisation — most starkly, the hallucinatory voice in psychotic delusion (Schreber's interrupted sentence, Sie sollen werden…). That voice arrives as a pure gap, a cut in the symbolic, and the subject's response is an effortful push to make it signify, to recruit it into a chain of meaning. The fatigue is the somatic afterglow of that impossible exertion. Signifiantisation is therefore not ordinary speech-production or even repression in the classical sense; it is the forced, symptomatic attempt to master the Real of the voice — the voice as objet petit a — by rendering it a signifier.

The concept marks the limit-point of the subject's relation to the Other. Where the signifying chain normally generates meaning through metonymic sliding and metaphoric substitution, signifiantisation describes the effort to extend that chain into a zone where it cannot fully reach — where the object-voice exceeds the symbolic and instead "swallows" the subject. The paradox Lacan identifies is structural: the very effort to signifiantiser produces, as its trace, a breakdown (fatigue, symptom) rather than successful symbolisation. This aligns with the broader Lacanian principle that the signifier cannot represent the subject without producing a remainder, and that any attempt to close the gap in the Other from within the symbolic will only reproduce that gap in a new register.

Signifiantisation appears once in the corpus, in jacques-lacan-seminar-6 (p.401), at a pivotal moment in Lacan's elaboration of the voice as the third form of objet petit a. Its immediate theoretical neighbourhood is the analysis of the Schreber case and the structure of psychotic hallucination, where the voice arrives not as communicative speech but as a pure cut — a gap — that interrupts and overwhelms the subject. This locates signifiantisation at the intersection of the Gap and Objet petit a as cross-referenced canonicals: the gap is precisely what the subject's effort of signifiantisation attempts (and fails) to bridge, while the voice-as-objet-petit-a is the Real element that initiates the effort in the first place.

The concept also carries direct implications for the cross-referenced Desire and Metonymy. In normal desiring subjectivity, metonymic sliding allows the subject to sustain desire by moving from signifier to signifier without ever confronting the void directly. Signifiantisation names what happens when that sliding is blocked — when a piece of the Real (the hallucinatory voice) demands to be incorporated into the chain but cannot be seamlessly absorbed. The resulting effort is symptomatic rather than productive. By contrast, the cross-referenced Fantasy ($◇a) is precisely the structural formation that ordinarily shields the subject from having to perform this impossible conversion: fantasy frames reality so that the gap is held at bay. In psychosis, that frame is unavailable, and signifiantisation becomes the desperate, exhausting substitute. The concept thus functions as a specification of what goes wrong at the level of the signifier when the fantasy-support of desire collapses, and implicitly serves as a critique of Ego Psychology's adaptation model, which could never account for this kind of symptomatic, asymptotic labour of symbolisation.

this fatigue, which is symptomatic and paradoxical, seems conversely to be the aftermath or trace in the subject of an effort on his part to 'turn (or make) into signifiers' [signifiantiser], as I will call it.

The phrase "aftermath or trace" is theoretically loaded because it frames signifiantisation not as a successful act but as something legible only in its residue — the fatigue is the symptom that indexes an effort that has already spent itself without completing. The neologism "signifiantiser" (bracketed and explicitly named as Lacan's own coinage) simultaneously marks this as a technical intervention and insists that no existing psychoanalytic vocabulary had captured the precise labour of converting Real material into symbolic currency.
