Pronunciation

  • 5th-century BC Attic: /bá.tra.kʰos/[1]
  • 4th-century AD Koine: /ˈβa.tra.xos/[1]
  • 10th-century Byzantine: /ˈva.tra.xos/[1]

Forms

βᾰ́τρᾰχος (bátrakhos) m (genitive βᾰτρᾰ́χου); second declension[1] Ionic βάθρακος (báthrakos), with the aspiration moved; βότραχος (bótrakhos) (Hippocrates) and βρόταχος (brótakhos) (Xenophanes).[2][3] Hesychius records many more variants, among them βύρθακος (búrthakos) and a Cypriot βρούχετος (broúkhetos).[2][3]

Etymology

Beekes considers it Pre-Greek: the many variant forms, the alternation of α and ο, and a prenasalized form hidden in a corrupt gloss of Hesychius all point to a local word, partly reshaped by folk etymology and taboo.[2][4] He allows that it may have begun as an imitation of croaking, something like ⟨βρατ-αχ-⟩, compare the frogs' cry ⟨βρεκεκεξ⟩.[2] The DGE starts from a form with a syllabic /r/, which changed to the familiar forms by metathesis, and calls its origin, Pre-Greek or imitative, still debated.[5] Wiktionary sees an imitative word borrowed from Pre-Greek or from Semitic, comparing Biblical Hebrew צְפַרְדֵּעַ (ṣəp̄ardēaʿ, “frog”) and Arabic ضَفْدَع (ḍafdaʿ, “frog”).[1] Chantraine finds no established etymology, notes a suffix -χος (-khos) and asks whether Latin botrax (“lizard”) is related.[6][7]

Ancient writers derived it from βοή (boḗ, “cry”) and τραχύς (trakhús, “rough”), for its harsh croak.[8]

Earliest recorded meaning

The mock-epic Battle of Frogs and Mice, which tradition ascribed to Homer, uses it for the frog throughout;[9][7] among datable authors it first appears in Herodotus.[10][9]

Semantic evolution

In Attic it is the ordinary word for the frog, in Aristophanes, who also uses it for a wooden toy, and in Plato.[11] Theophrastus calls the tree frog the “green frog”.[9] Proverbs mocked a man who drinks water “like a frog” and those who “pour wine for frogs”, that is, give what nobody wants.[9] Aristotle and Aelian use the word for the angler fish, and late veterinary writers for the frog of a horse's hoof.[9][6] Hesychius also records it for a kind of hearth or grate.[6][2]

The Septuagint uses it for the frogs of Exodus, and the Revelation of John sees unclean spirits in the form of frogs.[12][13] Its diminutive βατράχιον (batrákhion) named the buttercups, plants of damp places, and Latin ranunculus is a translation of that name.[6][3]

Medieval vernacular Greek had many forms, such as βάθρακας (váthrakas) and βαθρακός (vathrakós), for the frog and the angler fish.[14] Modern Greek keeps βάτραχος (vátrachos), with a feminine βατραχίνα (vatrachína), and the everyday βατράχι (vatráchi) continues the ancient diminutive.[15][7]
