Pronunciation

  • 5th-century BC Attic: /dy.na.tós/[1]
  • 4th-century AD Koine: /ðy.naˈtos/[1]
  • 10th-century Byzantine: /ðy.naˈtos/[1]

Forms

δῠνᾰτός (dunatós) m (feminine δῠνᾰτή, neuter δῠνᾰτόν); first/second declension[1] Also of two terminations in Pindar.[2][3] Cretan νυνατός (nunatós) (Gortyn, 5th century BC), Boeotian διουνατός (diounatós) (Chaeronea), Aeolic δύνατος (dúnatos).[2]

Etymology

It is a verbal adjective formed from Ancient Greek δύναμαι (dúnamai, “to be able”) + -τός (-tós).[1][4][5]

The origin of δύναμαι (dúnamai) is uncertain.[5][6] Beekes and Chantraine analyse it as a present with a nasal infix that spread to the whole conjugation and to δύναμις (dúnamis); the Cretan νύναμαι (núnamai) is the same word, its /n/ probably by assimilation.[6][7] The LIV reconstructs Proto-Indo-European *dewh₂- (“to join”) and compares Tocharian B tsuwa (“joined”).[6] The unextended stem has also been compared with δήν (dḗn) and δηρός (dērós), words of duration, but both Beekes and Chantraine find no convincing link in meaning.[6][7]

Earliest recorded meaning

Its earliest uses are impersonal: Sappho has “it cannot be”, and Theognis “for this is not possible”.[3][4][2] Of persons, “able (to do something)”, it is found in Theognis and Pindar, “mighty to loose”.[8][3][9]

Semantic evolution

In classical prose it means strong in body or mind, able-bodied, and of ships, fit for service; of persons and states it means powerful and influential, and οἱ δυνατοί (hoi dunatoí) are the leading men.[3][8] The neuter forms many phrases, κατὰ τὸ δυνατόν (katà tò dunatón) “as far as possible” and ὡς δυνατόν (hōs dunatón) with a superlative, “as … as possible”.[3][2] Aristotle uses it for what is potential, as against what is actual.[3] The Geoponica speak of land as productive.[3]

In the Septuagint and the New Testament God is “the Mighty One”, and “all things are possible” for him.[10][2] Coptic borrowed the word as Coptic ⲇⲩⲛⲁⲧⲟⲥ (dunatos).[11]

Medieval Greek kept the word, and its medieval form and sense survive in Cretan.[12] In Modern Greek δυνατός (dynatós) means strong, able and also loud or intense (a strong pain, a loud noise); some senses are learned revivals of ancient ones, and the noun δυνατότητα (dynatótita, “possibility”) was coined in 1876.[13][4]

  • 5th century BC – A Gortyn inscription has the Cretan form νυνατός (nunatós).[2]
  • 4th century BC – Aristotle uses it for the potential.[3]
  • 1st century AD – The Gospel of Luke calls God “the Mighty One”.[10]
  • About AD 325 – The Coptic borrowing appears in a dated Sahidic manuscript.[11]
