The derivation
The word that opens Western literature's account of suffering — the μυρί᾽ ἄλγεα, the "countless sorrows" the wrath of Achilles deals the Achaeans in the proem of the Iliad — has an etymology that all three authorities treat with the same cautious gesture. They point to one connection and then back away from it.
The candidate is ἀλέγω "to take care, mind, heed." Beekes lays out the difficulty and the rescue in one breath: ἄλγος "is often connected with ἀλέγω. Although this has a different meaning 'to take care, mind, heed', a development to 'worry, grief' is conceivable" — and he reaches for a modern parallel to make the semantic bridge plausible, citing Dutch zorgen "to take care" beside English sorrow (Beekes, EDG s.v. ἄλγος). The same word, in other words, can slide from minding to being pained. He notes that Szemerényi (1964) "defends the identity."
Frisk reaches the identical verdict with characteristic economy: "Wahrscheinlich zu ἀλέγω" — probably to ἀλέγω (Frisk, GEW s.v. ἄλγος). Chantraine, for his part, declines to commit at all in the portion of his article that treats origins, dwelling instead on the word's behavior: ἄλγος is "souffrance physique," physical suffering, "ou souffrance en général," or suffering in general, and he records that it is given as a Cypriot word, glossed by the standard term for sharp bodily pain (Chantraine, DELG s.v. ἄλγος).
Where the dictionaries do disagree is on a second candidate. Frisk's Nachträge preserves the live dispute: Seiler connects ἄλγος with Latin algeō "to feel cold" — pain as the body's chill — while "according to Szemerényi" the word is rather syncopated from *ἄλεγος, again landing it back with ἀλέγω (Frisk, GEW Nachträge s.v. ἄλγος). So the question stands open between two readings: pain as cold-feeling (the Latin algeō line) and pain as the heeding that becomes grieving (the ἀλέγω line). Neither dictionary closes it.
Root
- Connection to ἀλέγω "to take care, heed" — favored, with caveats, by Beekes (after Szemerényi), Frisk ("probably"), via a semantic shift "heed → worry → grief" (cf. Dutch zorgen / English sorrow). Szemerényi: ἄλγος < *ἄλεγος syncopated.
- **Connection to Latin algeō "to feel cold"** — recorded by Frisk's Nachträge after Seiler; pain as the sensation of cold.
- No deeper Indo-European root is asserted with confidence; the comparatives ἀλγίων, ἄλγιστος show only that the ἀλγ- stem is old within Greek.
In the corpus
180 occurrences in the corpus. ἄλγος is, before anything else, a proem word: the Iliad announces itself as the song of a wrath that "put countless ἄλγεα on the Achaeans." It is the noun for what is undergone — physical pain and the grief that physical pain becomes — and it survives across the corpus as the standing word for suffering as a quantity, something that can be heaped up and counted (the polla algea, the "many sorrows"). The dictionaries note its productivity in compounds for localized pain: θυμ-αλγής (grieving the θυμός), καρδι-αλγής (pain in the heart, καρδία) — the soul's organs each take their own ἄλγος.
The word's world
ἄλγος names suffering as something accumulated rather than discharged. In the Homeric texture, the polla algea are the sufferings the hero bears and stores; David Claus places the word in a model where the same seat holds "extreme 'life'-affecting joy, grief, or despair," tracking a progression "from uses that we would probably call physical to ones we would consider psychological" (Claus, Toward the Soul). For David Konstan, grief sits awkwardly but legitimately among the Greek emotions — those states "attended by pain and pleasure" that change how people judge (Konstan, The Emotions of the Ancient Greeks). The etymology's hesitation is fitting: a word poised between cold-feeling and care-turned-sorrow names exactly the thing that begins in the body and ends in the soul.
