The derivation
ἀρετή is the Greek word for excellence, and the dictionaries cannot agree on where it comes from. What they agree on is what to rule out. Beekes opens by closing a door: ἀρετή is "not directly related to ἀρέσκω" — the verb "to please" — "for semantic reasons" (Beekes, EDG s.v. ἀρετή). The obvious neighbour is rejected. After that the three authorities scatter.
Beekes lists two live candidates and prefers neither outright. A connection with ἀρείων, "better" (the comparative "better, stronger"), is "semantically attractive, but formally not clear." The formally cleaner option, he reports, is Vine's: an analysis *h₂(e)r-etéh₂- "to the root of ἀραρίσκω" — the verb "to fit, to join, to fasten together" — "which would be formally excellent and for which he adduces semantic arguments." A third reconstruction, Nikolaev's *h₂nr-eteh₂-, derives ἀρετή "from the word for 'man, hero'" — that is, from ἀνήρ, making excellence literally manliness (Beekes, EDG s.v. ἀρετή). Three roots, three different stories about what excellence is: rightness, fittedness, or manhood.
Frisk frames the same uncertainty as a clean fork. "Die Bildung von ἀρετή ist nicht ganz klar" — the formation of ἀρετή is not entirely clear. One can take it "either as a primary formation from ἀρε- in ἀρέσκω," or — "wegen der Bedeutung besser," better, because of the meaning — "as a secondary formation from the nominal stem in" ἀρείων (Frisk, GEW s.v. ἀρετή). Where Beekes leans, hesitantly, toward the "fitting" root, Frisk leans, on grounds of sense, toward ἀρείων "better." He records Prellwitz's older guess too — an abstract *aro-s "fitting, good, suitable," "das Gut-sein," the being-good, marked "hypothetisch" — and Brandenstein's, which lands back at ἀραρίσκω: "Fügung, Fug," fitting, joining (Frisk, GEW s.v. ἀρετή). The candidates circle two ideas that keep surfacing: to be good and to be fitted together.
Chantraine declines the etymological fight almost entirely and tells the other story — the one the corpus will confirm. He notes only the importance of the word: "Le mot présente une grande importance dans l'histoire de la pensée grecque" (Chantraine, DELG s.v. ἀρετή).
Root
- ἀρέσκω "to please" — rejected by Beekes "for semantic reasons"; offered by Frisk only as the alternative he judges weaker than ἀρείων.
- ἀραρίσκω "to fit, join" (*h₂er-) — Beekes's "formally excellent" option (Vine 1998: *h₂(e)r-etéh₂-); Brandenstein independently ("Fügung, Fug"). Excellence as being well-fitted.
- ἀρείων "better" / *aro-s "good" — Frisk's preference "because of the meaning"; Beekes calls it "semantically attractive but formally not clear." Excellence as being better.
- ἀνήρ "man, hero" — Nikolaev 2005: *h₂nr-eteh₂-. Excellence as manliness. No consensus; the laryngeal-stem forms are OCR-garbled in the source (*h₂- written
h,) and quoted only as the dossier carries them.
In the corpus
1,936 occurrences — and the distribution tells the word's whole biography. ἀρετή is born in Homer, where it names the warrior's excellence, the "qualités du corps ou du cœur," qualities of body or heart (Chantraine) — yet Homer holds only 37 of the 1,936. The mass of the word lies centuries later, in prose: 691 occurrences in Aristotle (269 in the Nicomachean Ethics alone, 179 in the Politics, 128 in the Eudemian Ethics) and 612 in Plato (the Laws, the Meno, the Republic, the Protagoras). Two philosophers account for two-thirds of every ἀρετή in the corpus. The word climbed off the battlefield and into the ethical treatise — and kept going: 157 occurrences in Plotinus' Enneads mark its afterlife as a Neoplatonic technical term. In the New Testament it nearly vanishes (5); in the Septuagint (32) it mostly means the "praises" or "excellences" of God, the sense behind the late compound ἀρεταλόγος, the teller of "récits des miracles divins," accounts of divine miracles (Chantraine).
The word's world
ἀρετή is the word on which Greek ethics was built, and its history is a transfer of ownership. Arthur Adkins, the study Chantraine names, charts the decisive move: by the fourth century "the co-operative excellences have become aretai, and hence desirable… it is evidently this use of arete and kalon on whose attraction Aristotle is relying in writing the Ethics and Politics" (Adkins, Merit and Responsibility). The competitive excellence of the hero — strength, success, victory — is broadened into the cooperative virtues the philosophers could theorise as good in themselves. Chantraine draws the same arc in one sentence: the Homeric hero "vit et meurt pour incarner" the ideal ἀρετή symbolises; "cette vertu va bientôt s'exprimer dans la civilisation communautaire de la polis"; and "enfin avec Platon l'ἀρετή se trouve inséré dans un système philosophique et moral," bound up with the philosopher's ἐπιστήμη, knowledge (Chantraine, DELG s.v. ἀρετή). The endpoint is already visible in Heraclitus: Shirley Darcus Sullivan notes that he "describes this form of thinking (sophronein) as arete. Excellence is summed up in an intellectual activity" (Sullivan, Psychological and Ethical Ideas). Whatever its root — fittedness, betterness, or manhood — ἀρετή ended as the name for a human life lived at the top of its powers, and the Greeks spent a thousand years arguing about which powers those were.

All three FOUND as headword; the lemma is disentangled in the dossier from the homographs Ἀρήτη (queen of the Phaeacians, term arete-2) and the personified Ἀρετή (term arete-3), neither counted here. Competing roots — ἀρέσκω (rejected, Beekes), ἀραρίσκω (Vine 1998, Brandenstein), ἀρείων (Frisk, Prellwitz *aro-s), ἀνήρ (Nikolaev 2005) — per the three dictionaries; no consensus.
