Pronunciation

  • 5th-century BC Attic: /kʰǐː.li.oi̯/[1]
  • 4th-century AD Koine: /ˈçi.li.y/[1]
  • 10th-century Byzantine: /ˈçi.li.y/[1]

Forms

χῑ́λῐοι (khī́lioi) (feminine χῑ́λῐαι, neuter χῑ́λῐα)[1] Ionic χείλιοι, Doric χήλιοι, Lesbian and Thessalian χέλλιοι.[2][3]

Etymology

It is inherited from Proto-Hellenic *kʰehliyoi,[1] an adjective formed from Proto-Indo-European *ǵʰeslo- (“thousand”).[3][4] The dialect forms, Ionic χείλιοι (kheílioi), Doric χήλιοι (khḗlioi) and Lesbian and Thessalian χέλλιοι (khéllioi), point to an older *χέσλιοι (khéslioi); the Attic form is usually explained by assimilation of the vowels.[3][5][2]

Cognate with Sanskrit सहस्र (sahásra) and Avestan hazaŋra, “thousand”, whose first syllable is the zero grade of the word for “one” (εἷς (heîs)).[3][4] Latin mīlle is usually connected too, from *smih₂ ǵʰeslih₂.[3] The original concrete sense of the Indo-European word is unknown: Chantraine notes that Indo-European had no word of its own for “thousand”, and Beekes suggests something like “heap”.[4][3] Wiktionary derives it from *ǵʰes- (“hand”), the root of χείρ (kheír), as if “a full hand”.[1]

Earliest recorded meaning

Homer has it only in the neuter: the Iliad speaks of a thousand measures of wine (7.471) and a thousand fires burning on the plain (8.562).[2][6] Beekes notes that the Attic form intruded into the text of Homer, and LSJ that the Ionic χείλιοι should probably be restored there.[3][2]

Semantic evolution

Herodotus uses the singular with collective nouns, χιλίη ἵππος “a thousand horse”, and Xenophon follows him.[2] In Attic the feminine plural χίλιαι, with δραχμαί understood, meant “a thousand drachmas” (Demosthenes).[2] Inscriptions record the dialect forms: Ionic χείλιοι at Chios and Doric χήλιοι at Sparta in the 5th century BC, and Thessalian χέλλιοι at Phalanna in the 2nd.[2]

In the New Testament the thousand years of the Revelation (20:2–7) are the millennium.[7] It survives as Modern Greek χίλιοι (chílioi), which continues the ancient word.[8]
