Etymology

It is a later present beside from Ancient Greek κυέω (kuéō, “to be pregnant”), made like the verbs in unaccented ⟨-ω⟩.[2][3][4] The aorist middle, “to conceive”, is much older, and LIV takes it as a root aorist.[5][4][6] The family goes back to Proto-Indo-European *ḱewh₁- (“to swell”),[1][4][5] and the older present matches Sanskrit श्वयति (śváyati, “swells, increases”), from *ḱuh₁-éye-.[4][5]

Earliest recorded meaning

The aorist middle, “to conceive”, is in Hesiod's Theogony; the present is first in Theognis, of a city “pregnant” with a tyrant.[2][7][8]

Semantic evolution

In the present it means to be pregnant, of women and female animals, sometimes with an object, the child or litter carried.[2][8] Aeschylus uses the active aorist causatively: the rain made the earth pregnant.[2][8] Chantraine notes that Attic forms of the present can often be read as κυέω (kuéō), and Beekes puts the sure attestations from Aristotle and the Septuagint on.[6][4]

It was used figuratively of a soul or a city “pregnant” with something.[2][3] Medieval vernacular Greek still knew the word, and it lives on in some Modern Greek dialects.[9]

Timeline

  • 6th–5th century BC – Aeschylus uses the aorist of the rain impregnating the earth.[2][8]
