French ↔ English neologism map

Lacan invented or repurposed many terms that don't translate cleanly. Translators disagree, and the choices matter — what reads as a clarification in one English version is a substantive interpretation in another. This page is a working glossary of the load-bearing French terms in the corpus, what they're translated as, and where the choices diverge.

Conventions: French in italics; standard English translations in bold; concept page links in brackets. Translator notes (Sheridan / Fink / Gallagher / Sheridan-revised / Forrester) are flagged where they matter.

The orders

French	English	Notes
le réel	the Real, the real	Real. Capital-R when used as a register; lowercase when generic. Common error: reading the Real as "reality" — it is precisely not reality.
le symbolique	the Symbolic	Symbolic. The order of language and law. Often unmarked in older translations.
l'imaginaire	the Imaginary	Imaginary. Of images, mirroring, ego — not of fantasy in the colloquial sense.
RSI	R.S.I. / Real-Symbolic-Imaginary	Borromean Knot notation. Title of Seminar XXII (we have Seminar XXII · R.S.I.Jacques Lacan · 1974).

Subject and Other

French	English	Notes
sujet	subject	Subject. Lacan keeps the philosophical sense (the I of I think) but splits it from the ego.
je / moi	I / ego	Lacan distinguishes the je of speech from the moi of self-image. Fink renders both as "I" / "ego" with footnote disambiguation; older translators sometimes lose the distinction.
Autre (capital) / autre (lowercase)	Other / other	The big Other / Little Other. The capital is structural (language, law, the unconscious as discourse of the Other); the lowercase is the imaginary peer. Always check capitalization — older Sheridan translations sometimes flatten this.
Autre barré (Ⱥ)	barred Other	The Other-with-a-bar: the Other lacks too. Late-Lacan move with Bruce Fink rendering it as S(Ⱥ) — "the signifier of the lack in the Other."
sujet barré ($)	barred subject	Splitting of the Subject. Same logic, applied to the subject side.

The lost objects

French	English	Notes
objet petit a	objet petit a / object a / object little a	Objet petit a. Lacan instructed translators to keep the French untranslated to mark its technical status. Fink uses objet a; Sheridan uses "object a"; some commentators use l'objet a. The "petit" refers to autre (lowercase) as opposed to the big Other.
plus-de-jouir	surplus enjoyment / surplus jouissance	Surplus-jouissance. Coined on the model of Marx's Mehrwert (surplus value). McGowan and Žižek often render it as "surplus enjoyment."

Jouissance varieties

French	English	Notes
jouissance	jouissance (untranslated)	Jouissance. Sometimes "enjoyment" but loses the violent / painful / excessive sense. Fink keeps jouissance.
jouissance phallique	phallic jouissance	Phallic Jouissance. The jouissance available to the Subject inscribed under the Phallic Function.
jouissance Autre / jouissance autre	Other jouissance / other jouissance	Other Jouissance. Capital A in Lacan, lowercase in some commentators. The jouissance inscribed under the "feminine side" of Sexuation. Encore's great enigma.
jouis-sens	enjoy-meant / joy-in-meaning	Lacanian pun: jouissance + sens (meaning). Sometimes left untranslated.

The signifier

French	English	Notes
signifiant	signifier	Lacan's most important word, taken from Saussure but radically rethought.
S1 / S2	master signifier / knowledge	Mathematical notation. Master Signifier is the empty signifier that quilts; S2 is the chain of signification (knowledge / savoir).
point de capiton	quilting point, anchoring point, upholstery button	Point de capiton. Literally the button that fixes the upholstery; figuratively the signifier that retroactively fixes meaning in a discourse.
lalangue	lalangue (untranslated)	Lalangue. Lacan's late-period invention: not language as system but the babbling, polyphonic, jouissance-laden material of speech. Fink keeps lalangue; older translators sometimes paraphrased disastrously.

Le nom

French	English	Notes
Nom-du-Père	Name-of-the-Father	Name of the Father. The signifier installing the Paternal Function. Hyphenated to mark its status as a signifier-formula, not a person.
Noms-du-Père	Names-of-the-Father	Plural form. Seminar XXI makes this plural — there are names (multiple paternal signifiers) of the father.
fonction paternelle	paternal function	Paternal Function. The structural role, distinct from any actual father.
forclusion	foreclosure	Foreclosure. The Lacanian operation that produces Psychosis. Older translations sometimes use "rejection."

Operations and structures

French	English	Notes
aliénation	alienation	Alienation. In Lacan, paired with Separation — the two operations constituting the subject in Seminar XI. Not the Hegelian-Marxist alienation Lacan critiques.
séparation	separation	Separation. The second moment after alienation; the subject's response to Lack in the Other.
vel	vel (untranslated)	The "either…or" Lacan uses to describe the alienating choice. From Latin.
aphanisis	aphanisis (untranslated)	Aphanisis. From Ernest Jones; Lacan rethinks it as the fading of the subject under the signifier.
parlêtre	speaking-being / parlêtre	Late Lacan's portmanteau: parler (to speak) + être (being). Names the human as essentially a speaking-being. Often kept untranslated.
extimité	extimacy	Extimacy. Extérieur + intimité: an outside that is most intimate, an inside that is exterior. Most central object: Das Ding.
méconnaissance	misrecognition / miscognition	The Ego's constitutive blindness about itself. From the Mirror Stage onward.

Negation and the not-all

French	English	Notes
pas-tout	not-all / not-whole	Not-all. The "feminine side" of the formulas of Sexuation: pas-tout is subject to the Phallic Function. Different translators render it differently with substantial interpretive consequences — Copjec and Žižek's disagreement on Encore turns partly on this.
Il n'y a pas de rapport sexuel	There is no sexual relation / There is no sexual relationship	The famous late thesis. Rapport doesn't only mean "intercourse" — it means relation, ratio, written formula. The claim is that no formula in the Symbolic writes the sexed relation.

Topology

French	English	Notes
bande de Möbius	Möbius strip	Topological figure for the unity-in-twist of inside and outside.
cross-cap	cross-cap	A Möbius-like surface used in late Lacan's models of the Subject.
nœud borroméen	Borromean knot	Borromean Knot. Three interlocked rings that fall apart if any one is removed; Lacan's late model of Real / Symbolic / Imaginary.
sinthome	sinthome (untranslated)	Sinthome. Lacan's archaic spelling of symptôme — "the fourth ring" that holds the Borromean knot together. Seminar XXIII.

Other key idioms

French	English	Notes
l'achose	the not-thing / a-thing / achose	Late Lacan: a portmanteau of autre + chose, signaling the Thing in its Otherness. Rarely translated cleanly.
les non-dupes errent	the non-duped err	Les Non-Dupes Errent. Title of Seminar XXI. The "non-dupes" — those who refuse to be taken in by the Symbolic — are the ones who go astray. Pun on non-dupes errent / Nom-du-Père (homophonic).
sujet supposé savoir	subject supposed to know	Subject Supposed to Know. The subject the analysand presumes is in the analyst — the structural position that drives the transference.
savoir / connaissance	knowledge (uncomfortably)	French distinguishes savoir (knowing-that, knowledge as system) from connaissance (acquaintance, knowing-how). Lacan exploits this distinction; English flattens it. The `Knowledge` page tracks where the distinction is load-bearing.
moins-phi (-φ)	minus-phi	Phallus in its negated / castrated form. Used in formulas alongside moins-phi and grand-phi (Φ).

Translation choice cheat-sheet

If you see…	…prefer the form	Because…
"object a"	objet petit a	The translation "object a" loses the petit / Other-distinction.
"the gap" / "the void"	check French	Could be béance, trou, vide — all carry different theoretical weight
"lack" without context	check French	manque (lack), défaut (defect), à-être (to-be) all get translated as "lack"
"feminine sexuality"	careful	Lacan's sexualité féminine refers to a position in Sexuation, not anatomical gender.
"object" (capital O)	usually Chose (Thing)	Das Ding; rendered Thing or the Thing in Fink.
