Pronunciation

  • 5th-century BC Attic: /é.oi̯.ka/[1]

  • 10th-century Byzantine: /ˈe.y.ka/[1]

Forms

ἔοικᾰ (éoika) [1]

Etymology

It is an old intransitive perfect with present meaning, *ϝέϝοικα (*wéwoika), dual *ϝέϝικτον (*wéwikton), pluperfect *ἐϝεϝοίκει (*ewewoíkei) (whence ἐῴκει (eṓikei)); the metre of Homer shows the lost /w/.[2][3] Ionic οἶκα (oîka) arose from it by the loss of a vowel.[2][4]

The root is perhaps inherited from Proto-Indo-European *weyk- (“to be fitting, become equal”), but there are no certain cognates outside Greek.[2][1] The comparison with Lithuanian į-vỹkti (“to occur, happen”) and pavéikslas (“example”) is doubtful, and Wiktionary thinks the Lithuanian word belongs to a separate root meaning “to overcome”.[2][1]

Greek built new verbs on the perfect: *ϝεϝίκσκω (*wewíkskō) gave ἐΐσκω (eḯskō) “to liken”, and *ϝεϝικάζω (*wewikázō) gave Homeric and later εἰκάζω (eikázō) “to compare, guess”.[2][3] The noun εἰκών (eikṓn) “likeness” has no reduplication.[2]

Earliest recorded meaning

In the Iliad it means “to be like, look like” someone in form, size or voice, and its participle ἐοικώς (eoikṓs) “like” is frequent.[4][5][6] The impersonal use “it is fitting”, usually negated, is also Homeric: “it is not possible, nor is it fitting, to refuse”.[4][6]

Semantic evolution

From “resembling” came “seeming”: with an infinitive or a participle, a person “seems” to do something, and the parenthetic “as it seems” (Ionic “as it seems” with οἶκε (oîke)) became common in Herodotus, Sophocles and Euripides.[4][6] Plato used “as it seems” to soften a statement, almost “probably, I think”.[4]

The neuter participle εἰκός (eikós) became a word of its own: “fitting, reasonable”, and then “likely, probable”; in Herodotus, Thucydides, Plato and Aristotle it is “probability”, and in Aristotle a probable proposition as opposed to a fact.[6][4] Plotinus used the verb for being analogous to something.[4]

In the New Testament the Letter of James compares the doubter to a wave of the sea and the hearer who does not act to a man looking in a mirror.[7]
