ὑπνόω (hupnóō) [1]
Etymology
It is a denominative verb from Ancient Greek ὕπνος (húpnos, “sleep”) with the suffix -όω (-óō).[1][2][3] The noun goes back to Indo-European Proto-Indo-European *swep- (“to sleep”), as the zero-grade noun *sup-no-.[4][5] Cognate with Albanian gjumë and Old Church Slavonic сънъ (sŭnŭ), from the same formation, and with Sanskrit स्वप्न (svápna) and Latin somnus.[4]
Earliest recorded meaning
Herodotus uses the passive perfect participle ὑπνωμένος, “asleep”.[6][7]
Semantic evolution
In Classical Greek the verb is rare: besides Herodotus, Aristophanes has a Laconian form of the infinitive, and the Hippocratic Epidemics uses the active for sleeping.[6][7] It became common in Hellenistic prose (Polybius, Plutarch).[7][8] The Septuagint uses it for sleep, for causing to sleep (Genesis 2:21), and euphemistically for dying.[9][6] The transitive sense “to put to sleep” is found in Dioscorides.[6][10]
Its derivative ὑπνωτικός (hupnōtikós) “putting to sleep” passed through Late Latin and French into English hypnotic.[11]
