Forms

ἀκᾰκίᾱ (akakíā) f (genitive ἀκᾰκίᾱς); first declension[4]

Etymology

The word for the acacia is probably Pre-Greek, in Beekes's view a substrate word.[5][6] Furnée compared κάκτος (káktos); if the two belong together, ἀκακία would have the prothetic vowel and the variation between /k/ and /kt/ found in other Pre-Greek words.[6] Beekes also compares the plant name ἀκακαλίς (akakalís), and Frisk calls the word foreign.[5][7] Scarborough's database rates the Pre-Greek origin as highly reliable.[8]

Others look abroad: Chantraine assumed an Oriental origin, for which Beekes sees no reason.[5] Kramer compared Coptic ⲕⲁⲕⲉ (kake, “darkness”), from the dark colour of the wood, with the first vowel taken over from ἄκανθος (ákanthos), but Beekes finds this unconvincing.[5] Wiktionary accepts the Coptic source and traces it to Egyptian kkw (“darkness”).[4] The DGE calls it a borrowing of unknown origin, and Triantafyllidis and Babiniotis a possible Eastern loan.[2][3][9] Babiniotis adds that the tree name was probably linked by popular etymology with ἀκακία “guilelessness”.[9]

Earliest recorded meaning

It is first found in the Hippocratic treatise Diseases of Women, as the name of a plant.[8][10][9]

Semantic evolution

In the medical writers of the Roman period it is the gum-yielding acacia of Egypt and also a kind of broom, Genista acanthoclada.[1][2] Dioscorides describes both, and Aretaeus uses it in his remedies.[1][2][5] Papyri of the 2nd and 3rd centuries AD mention it too.[2] Coptic borrowed it, with forms recorded from about AD 600.[11]

Medieval Greek used the word for the flowers and the gum of the plant.[12] Modern Greek ακακία (akakía) is a learned revival, the name of a family of trees and shrubs with thorny branches and small round flowers.[3] English took acacia from Latin in the 1540s.[13]

Pronunciation

  • 5th-century BC Attic: /a.ka.kí.aː/[4]
  • 4th-century AD Koine: /a.kaˈci.a/[4]

Forms

ἀκᾰκίᾱ (akakíā) f (genitive ἀκᾰκίᾱς); first declension[4]

Etymology

The word for guilelessness is formed from Ancient Greek ἄκακος (ákakos, “guileless”) + -ία (-ía), an abstract noun from the adjective.[1][14][4] The adjective is made of the privative ἀ- (a-, “not”) and κακός (kakós, “bad”).[4]

Earliest recorded meaning

It is first found in the 4th century BC, in Demosthenes and Aeschines, for innocence that knows no evil, the simplicity of the inexperienced.[1][2][10]

Semantic evolution

Aristotle's Rhetoric speaks of people who measure their neighbours by their own guilelessness.[2][1] In the Septuagint it is the integrity of the righteous, Job above all, and the Psalms use it too.[2][10] Philo applies it to Adam and Eve before the fall.[2] In 1 Clement and the Shepherd of Hermas it is a Christian virtue, joined with simplicity and personified.[15]

Medieval vernacular Greek still used it for innocence and naivety.[12]
