Pronunciation

  • 5th-century BC Attic: /ktá.o.mai̯/[1]
  • 4th-century AD Koine: /ˈkta.o.mɛ/[1]
  • 10th-century Byzantine: /ˈkta.o.me/[1]

Forms

κτᾰ́ομαι (ktáomai) [1] Future κτήσομαι (ktḗsomai), aorist ἐκτησάμην (ektēsámēn), perfect κέκτημαι (kéktēmai) and ἔκτημαι (éktēmai), future perfect κεκτήσομαι (kektḗsomai), passive aorist ἐκτήθην (ektḗthēn).[2][3] Ionic κτέομαι (ktéomai) only as a variant reading in Herodotus.[3]

Etymology

In Beekes's view it is probably inherited from Proto-Indo-European *tkeh₁- (“to rule, gain, acquire”), comparing the Indo-Iranian present Avestan xšaiieiti (“rules, has power”) and its Sanskrit counterpart, which fits well in meaning.[4] All the Greek forms have ⟨κτη-⟩ except the present itself, which is rather rare and late, and their ⟨η⟩ confirms a root ending in *h₁.[4] Since the two presents do not match well in formation, LIV gives up this etymology and derives the verb from a noun *tk-eh₂- (“possessions”).[4] Wiktionary likewise starts from *tk-éh₁- (“acquisition”), of *tek- (“to take by the hand; to receive, obtain”).[1] Pokorny set up a root *kþē(i)- (“to acquire, possess”).[5]

Beekes also assumes an old heteroclitic noun, Proto-Greek *ktē-war, behind κτέαρ (ktéar) and κτέανα (ktéana, “possessions”).[4]

Earliest recorded meaning

In Homer it means to acquire or win, and in the perfect to possess: the Iliad speaks of the possessions that Peleus acquired, and the Odyssey of slaves acquired by Odysseus.[6][2][4]

Semantic evolution

From the tragedians and Thucydides on it is used of gaining things that are not material, such as power, skill or goodwill, and of gaining persons: a wife, friends, allies, children by a woman.[2][3] Sophocles uses it of bringing death or a goddess's anger on oneself.[3] Demosthenes says that “it often seems harder to keep good things than to acquire them” (τὸ φυλάξαι τἀγαθὰ τοῦ κτήσασθαι χαλεπώτερον).[3] In comedy and Plato the participle means an owner or master of slaves.[2]

In the New Testament it means to procure or get, of gold for one's belt or the gift of God bought with money, and “all I get” is a man's income.[7] Coptic borrowed it; its earliest dated manuscript is of 625.[8] Medieval Greek kept κτώμαι (któmai), with the Pontic form χτήσκουμαι.[9] Modern Greek uses the compound αποκτώ (apoktó, “to acquire”), an active form of the ancient ἀποκτάομαι (apoktáomai).[10][11]
