Pronunciation

  • 5th-century BC Attic: /ka.tá/[1]
  • 4th-century AD Koine: /kaˈta/[1]
  • 10th-century Byzantine: /kaˈta/[1]

Forms

κᾰτᾰ́ (katá) (governs the genitive and accusative)[1] Dialect κάτ, assimilated to the next consonant (κὰδ before δ, κὰκ before κ, κὰπ before π…); elided κατ᾽, and καθ᾽ before a rough breathing.[2][3] Also καται- in compounds such as καταιβάτης (kataibátēs), an epithet of Zeus, and Arcadian κατύ.[4][5] It may follow its noun with the accent thrown back (Λυκίην κάτα “in Lycia”).[2]

Etymology

It is inherited from Proto-Hellenic *kətá,[1] from Indo-European Proto-Indo-European *km̥t- “down, with, along”.[4][6] It is identical with Hittite kattan “below, underneath” and katta “along with”, and the old Celtic word for “with”, Old Welsh cant and Old Irish cét-, probably belongs here too.[4][5][7] Beekes and Frisk leave open a further link with Indo-European *kom, the source of Latin cum, and Wiktionary reconstructs *ḱm̥-th₂ from *ḱóm “beside, with”.[4][5][1] The by-forms καται- (katai-) and Arcadian κατύ (katú) are best explained as made on the model of παραί (paraí) and ἀπύ (apú).[4][5]

Earliest recorded meaning

From Homer on it is an adverb and a preposition with the genitive and the accusative.[4][8][9] Homer uses it with the genitive for movement down from heaven, mountains or horses and down into the earth, and with the accusative for movement down along a stream, over the sea and throughout a city or a camp.[2][10]

Semantic evolution

Chantraine explains the uses from a general sense of fitting oneself to something: with the accusative “towards, in accordance with”, with the genitive “down from” and “against”.[7] Greek paired it with ἀνά (aná) as opposites, κατά “downwards” against ἀνά “upwards”, and Homer's adverb κάτα “below” was later replaced by κάτω (kátō).[7] The genitive developed the hostile sense “against” someone, and the accusative the distributive sense (κατὰ φυλάς “tribe by tribe”, καθ᾽ ἡμέραν “every day”) and the sense of conformity, as in κατὰ φύσιν “naturally” and κατὰ δίκην “justly”.[2][8]

As a prefix (κατα-) it expresses movement downwards, return, and very often the completion of an action, as in κατακτείνω (katakteínō) “kill outright” and καταφαγεῖν “eat up”.[7] The Septuagint and the New Testament use both cases often, with the genitive for “down from” and “against” and with the accusative for “according to”.[11][12] Coptic borrowed it as ⲕⲁⲧⲁ (kata), attested from about AD 200.[13] Latin borrowed it as cata, and English uses the learned prefix English cata-.[1][6]

Modern Greek κατά (katá) keeps many of the old uses with the accusative; its use with the genitive for “against” is a learned semantic loan from French contre.[3]

Timeline

  • Homer – The Iliad uses it with the genitive for “down from” and with the accusative for “down along, throughout”.[2][9]
  • 5th century BC – Herodotus uses it with the accusative for “at or around” a time and “in the time of” someone.[2][14]
  • 5th century BC – Thucydides uses κατὰ μίαν of ships sailing one by one, in column.[2][14]
  • 4th century BC – Aristotle uses κατὰ κεφαλήν for “per head”.[2][14]
  • About AD 200 – Coptic borrows it as ⲕⲁⲧⲁ (kata).[13]
  • Modern Greek – κατά (katá) with the genitive takes the sense “against” from French contre.[3]
