The derivation
σάρξ means, first and plainly, flesh — the soft tissue on the bones, in Homer almost always plural, σάρκες. The dictionaries agree on a probable deep root and then disagree, instructively, about what it meant. All three trace σάρξ to the Avestan verb θβaras- "to cut," reconstructing an Indo-European *twerk-. On the "very considerable" view, Frisk writes, the root is "eig. 'schneiden'… als Simplex 'gestalten, erschaffen, bestimmen'" — properly "to cut," as a simplex "to shape, create, determine" — so that σάρξ would be, originally, "*'Schnitt,'" a cut, "wie lat. carō," like Latin carō "piece of flesh," cognate with κείρω, "to cut" (Frisk, GEW s.v. σάρξ). On this reading flesh is a cut piece: meat. Chantraine reports the same "taught" account — σάρξ "signifie 'morceau de viande' comme latin carō," a piece of meat whose root sense is "part" (Chantraine, DELG s.v. σάρξ).
But both Frisk and Chantraine then record a dissent, and both judge it. Ernst Risch objected that "σάρξ chez Hom. ne signifie pas 'part de viande'" — in Homer σάρξ does not mean a portion of meat — and that the Avestan root often "exprime… l'idée de 'fixer, donner une forme à,'" the idea of giving a form to something. Risch concluded that "σάρξ est ce qui donne sa forme à un être," flesh is what gives a being its form; Frisk renders it "Fleisch als das, was dem menschlichen Körper Gestalt und Formung gibt," flesh as that which gives the human body shape and form (Chantraine and Frisk, s.v. σάρξ). The two readings part on a fine but real point: is flesh what is cut from a body, or what gives a body its shape? The lexicographers come down against the elegant option — Chantraine calls Risch's analysis "discutable," debatable; Frisk, "gewiß nicht vorzuziehen," certainly not to be preferred. Beekes keeps to the "cut → shape, create, destine" root, citing Lubotsky on the zero grade (Beekes, EDG s.v. σάρξ).
One compound preserves the literal sense as a small grim fable. σαρκο-φάγος means "flesh-eating"; a limestone quarried at Assos was the λίθος σαρκοφάγος, the "flesh-eating stone," said to consume the corpses laid in it — and from that the word for the stone became the word for the coffin, passing into Latin as sarcophagus (Beekes and Frisk, s.v. σάρξ).
Root
- IE *twerk-, from the Avestan root θβaras- "to cut" — all three agree on the root, disagree on the sense.
- Majority "cut" reading: σάρξ = "a cut, a piece of flesh," like Latin carō (= Umbrian karu "pars"), to κείρω "to cut." Frisk's "very considerable" view; Chantraine's "taught" view; Beekes (via Lubotsky), without the carō equation.
- Risch's "form-giving" reading: σάρξ = "what gives a being its form." Judged "debatable" (Chantraine) and "certainly not to be preferred" (Frisk); the Hittite tuekka- "body" link "most doubtful."
In the corpus
455 occurrences — and σάρξ is, above all, the word of the Bible. Of the 455, 191 fall in the Septuagint and 110 in the New Testament — 301, two-thirds, are scripture. In the LXX σάρξ renders the Hebrew basar (Genesis 30, including "all flesh"; Leviticus 18; Job; the Psalms; Sirach). In the New Testament the density is unmistakably Pauline — Romans 18, Galatians 11, 1 Corinthians 10, 2 Corinthians 8, Ephesians and Colossians 6 apiece — roughly sixty occurrences in the letters of Paul, the σάρξ that "wars against the spirit." John adds thirteen, including the claim that "the Word became σάρξ" (John 1:14). Yet σάρξ did not begin in scripture: its classical home is the body's anatomy — **Plato's Timaeus (42), Aristotle's Metaphysics (23), Plotinus' Enneads (13)** — where it means simply muscle and tissue. A plain word for meat became the theological name for what the human being is when measured against God.
The word's world
In Greek, σάρξ was bodily tissue; in Paul, it became a verdict on the human condition. Albrecht Dihle warns against the obvious misreading: the Pauline term "does not, or at least not primarily, point to the dualism of matter and spirit." Rather, "σάρξ (flesh), as opposed to pneuma (spirit), denotes… the empirical condition of man, in which all his activity, including his religious, intellectual, and moral endeavor, finds its ultimate goal in himself" (Dihle, The Theory of Will in Classical Antiquity). Flesh, here, is not matter but self-enclosure — the creature turned toward itself and away from God. And it is a battlefield: Richard Sorabji notes that when "St Paul says that flesh and spirit war against each other, so that we do not do what we will to do," the Fathers were driven to ask whether this meant two wills, or two souls, in one person (Sorabji, Emotion and Peace of Mind). It mattered, too, that σάρξ was not σῶμα: the flesh that opposes the πνεῦμα is the mortal, sin-prone creature, not the body as such. The etymology argued over whether flesh is what is cut or what gives form; the corpus shows the answer the dictionaries did not reach for — that σάρξ became the Greek for what we are, and cannot, by ourselves, escape.
Authorities: Beekes, Etymological Dictionary of Greek (Brill 2010) s.v. σάρξ (scan pp. 1360–1361, #5430); Chantraine, Dictionnaire étymologique de la langue grecque s.v. σάρξ (scan pp. 1008–1009, #7114 + the Σάρξ/Et. continuation #7115, scan p. 1009); Frisk, Griechisches etymologisches Wörterbuch s.v. σάρξ (scan pp. 1651–1652, #5076). All three FOUND as headword. The root (Avestan θβaras- "to cut," IE *twerk-) is shared; the sense is disputed — the "cut / piece of meat" reading (Latin carō, κείρω: Frisk's "very considerable" view, Chantraine's "taught" view, Beekes) versus Risch's "what gives form" reading (Risch, Sprache 7, 1961), which Frisk calls "certainly not to be preferred" and Chantraine "debatable." σαρκοφάγος → "coffin" → Lat. sarcophagus per all three. The lemma resolves cleanly with no homograph; the σαρκ- derivatives are counted separately; σάρξ was borrowed into Coptic as ⲥⲁⲣⲝ (soul-map §13).
