Body
ELI5
The "body" here means the raw, pre-verbal stuff of our physical existence that all talking and meaning-making has to grab onto — but can never fully explain or control — and the question Lacan is asking is: how does any system of language or social rules actually manage to get a grip on something so unruly?
Definition
In Seminar 19 (...ou pire), Lacan's concept of the Body designates the pre-discursive material substrate — neither organism nor psychosomatic unity — from which meaning emerges but which itself remains radically "unconstructed" by discourse. The body is posited as the originary site of jouissance: it is what discourse must "catch hold of" in order to constitute a social bond, yet it persistently exceeds any discursive capture. The body is not the biological body of anatomy, nor the imaginary body of the ego, but something closer to the surface of inscription on which signifiers land and from which surplus-jouissance is extracted. Crucially, the body in this passage is positioned as the recalcitrant underside of the Four Discourses — the element that the formal tetrad of semblance, truth, enjoyment, and surplus-jouissance must grapple with without ever fully absorbing.
The theoretical weight of this concept comes from its function in articulating a constitutive gap within discourse itself. Lacan argues that all discourse operates as discourse of semblance — a formal arrangement that installs itself over a void. The body names that void at its most concrete: it is the "level" from which all meaning arises precisely because it is what meaning cannot fully constitute. The analytic discourse is distinguished, in this context, by placing objet petit a in the position of semblance — that is, by letting the object-cause of desire, which is always a fragment of the body (voice, gaze, breast, feces), operate as the commanding agent. This means the Discourse of the Analyst intervenes specifically in the gap between body and discourse, a gap the other three discourses paper over or exploit without acknowledging.
Place in the corpus
Within jacques-lacan-seminar-19, this concept of the Body functions as the grounding problem for the entire theory of the Four Discourses. If discourse is always discourse of semblance — a formal arrangement requiring exactly four structural positions — then the body is what lies outside that formalism yet makes it necessary: it is the site of jouissance that each discourse attempts to organize. The concept is thus intimately linked to Jouissance (the body as the seat of enjoyment that discourse extracts and partially captures as surplus-jouissance) and to the Four Discourses (each of which is, at bottom, a different strategy for "catching hold" of bodies).
The concept is most precisely a specification of the relationship between the Discourse of the Analyst and the other three discourses. Where the Discourse of the Master commands the body through the Master Signifier (S1 → S2, with jouissance escaping as the unrecognized remainder), and the Discourse of the University processes bodies as objects of knowledge, the Discourse of the Analyst — by placing objet petit a in the agent position — uniquely acknowledges the body's status as the unconstructed origin of meaning. The Fantasy ($◇a) is also implicated here: fantasy is what ordinarily bridges the gap between the body and discourse, giving desire its coordinates; the analytic discourse dissolves this bridge. The Body as "unconstructed" is thus both the problem all discourses must solve and the Real that the analytic discourse, uniquely, does not pretend to fully resolve.
Key formulations

what happens at the level of the body, from which all meaning arises, but unconstructed...the question is posed of how this discourse has succeeded in catching hold of bodies.
The phrase "from which all meaning arises, but unconstructed" is theoretically loaded because it simultaneously asserts the body as the origin of meaning and its irreducibility to any discursive construction — positioning the body as a Real that is productive yet resistant; the verb "catching hold of" then frames discourse not as something that transparently represents or reflects the body, but as something that must actively seize a substrate that fundamentally escapes it.

Theoretical move: Lacan argues that discourse is always discourse of semblance, and that the Four Discourses—grounded in the tetrad of semblance, truth, enjoyment, and surplus-jouissance—are held together not by their content but by the formal necessity of the number four and its vectors; the analytic discourse is distinguished by placing the objet petit a in the position of semblance, thereby intervening in the gap between body and discourse.
