Pronunciation

  • 5th-century BC Attic: /heb.do.mɛ̌ː.kon.ta/[1]
  • 4th-century AD Koine: /eβ.ðoˈmi.kon.ta/[1]
  • 10th-century Byzantine: /ev.ðoˈmi.kon.ta/[1]

Forms

ἑβδομήκοντᾰ (hebdomḗkonta) (ordinal ἑβδομηκοστός, adverbial ἑβδομηκοντᾰ́κῐς)[1] Doric (Delphi, the Heraclean Tables) and Thessalian forms begin ἑβδεμ-, and Boeotian forms in ἑβδομει- are found on inscriptions of the 3rd century BC.[2][3]

Etymology

It is inherited from Proto-Hellenic *hebdmākontə,[1] from an older *ἑβδμήκοντα (*hebdmḗkonta), inherited from Proto-Indo-European *septm-dḱmt- (“seventy”).[4][1] Frisk explains the ⟨βδ⟩ by assimilation: the numeral *septm̥ (Greek ἑπτά (heptá)) became *sebdm- before the voiced stop of the word for “ten”.[2] Beekes follows Kortlandt in deriving the long vowel of -μη- from the syllabic /m/ followed by a preglottalized /d/, which gave the same result as *-m̥h₁-.[4] The same development is seen in ἕβδομος (hébdomos) “seventh” and in ἑβδομάς (hebdomás) “a group of seven”.[4][2]

Cognate with Sanskrit सप्तति (saptati), Latin septuāgintā and Old Armenian եօթանասուն (eōtʻanasun).[1]

Earliest recorded meaning

Herodotus uses it for the number seventy, reckoning a long human life at seventy years.[5][3][4]

Semantic evolution

The word stayed an indeclinable numeral throughout antiquity, used in prose from Herodotus and Xenophon on and in the Septuagint and the New Testament.[5][6][7][8] In Hellenistic Greek the plural phrase “the Seventy” came to mean the translators of the Hebrew Bible into Greek, and by metonymy their translation.[9][10]

In medieval vernacular Greek it lost a syllable and became εβδομήντα (evdomínta), on the model of εξήντα (exínta) and πενήντα (penínta), which is the ordinary Modern Greek word.[11][9] The ancient form lives on in Modern Greek only as a learned word, chiefly in the name Modern Greek Εβδομήκοντα (Evdomíkonta) for the Septuagint translators.[9]
