Forms
ᾰ̓δῠ́νᾰτος (adúnatos) m or f (neuter ᾰ̓δῠ́νᾰτον); second declension[1]
Etymology
It is formed from Ancient Greek ἀ- (a-, “not”) + δυνατός (dunatós, “able, possible”),[1] the adjective being from δύναμαι (dúnamai, “to be able”) with the verbal suffix -τός (-tós).[1] Beekes analyses the verb as a present with a generalized nasal infix (⟨δύ-ν-α-μαι⟩) and reports LIV's root Proto-Indo-European *dewh₂- (“to join together”), but leaves the origin open.[2]
Earliest recorded meaning
Pindar's second Pythian ode calls something impossible, and Epicharmus uses it of someone unable to keep silent.[3][4][5]
Semantic evolution
Of persons it means unable to do something (Herodotus, Euripides) and, without a complement, weak or without strength (Herodotus, Euripides, Lysias).[4][5] At Athens οἱ ἀδύνατοι were the disabled citizens who received public relief, as in the title of Lysias' 24th speech and in Aristotle's Constitution of the Athenians.[4][5] It also means poor (Thucydides), of no power or importance (islands, a city), and of a ship, disabled, while Polybius uses it of barren land.[4][5] Attic curse tablets ask for enemies to be made powerless.[5]
Of things it means impossible, from Pindar and Euripides on, and Democritus speaks of hopes that cannot be fulfilled.[4][5] In Aristotle's logic the reduction to the impossible is ἡ εἰς τὸ ἀδύνατον ἀπαγωγή.[4] In the New Testament it describes a man unable to use his feet, the weak in faith, and what is impossible for people but not for God.[6][5]
Modern Greek αδύνατος (adýnatos) continues it, meaning weak, thin, impossible, and poor at a subject.[7]
