Etymology and origin of the Ancient Greek word ἰάομαι

Confidence
Uncertain
First attested
700s BC Homer, Iliad More words from the 8th century BC
Derivations
ἰατρός (iatrós)

Pronunciation

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

Forms

ῑ̓ᾰ́ομαι (īáomai) [1] Ionic future ἰήσομαι, aorist ἰησάμην; passive aorist ἰάθην, Ionic ἰήθην; perfect ἴαμαι in the Gospel of Mark.[2][3] Mycenaean Greek i-ja-te on the Mycenaean tablets, which Frisk takes, with a query, as the noun ἰατήρ (iatḗr, “physician”).[4][2]

Etymology

The origin is uncertain.[2][4] Schwyzer took ἰάομαι as a thematic remaking of an older athematic present, still seen in the Homeric name Ἰαμενός (Iamenós) and perhaps in Cypriot ἰjᾶσθαι (ijâsthai).[2][4] The old comparison with ἰαίνω (iaínō, “to warm, cheer”) is doubted by Schulze and Frisk;[4][2] García Ramón derives both verbs from the root Proto-Indo-European *h₁eysh₂- (“to strengthen, propel”), with the long ī- spread from a reduplicated present, and Wiktionary follows this.[2][1] The initial vowel is long in Homer and later also short.[2][3]

Earliest recorded meaning

It is found from Homer on, meaning to heal or treat: the Iliad uses it of treating a man, the Odyssey of healing an eye.[3][5][6]

Semantic evolution

In the present and imperfect it often meant “to treat, attempt to cure”, of patients, diseases and wounds, while the aorist meant “to heal”; the passive aorist meant “to be healed, recover”.[3][5] Pindar, the tragedians and Plato used it of diseases, and by metaphor of remedying grief, misfortune or wrongdoing;[3][5] Plato also used it for repairing damage, and in the Symposium Love heals human nature.[3][5] A proverb in Herodotus and the tragedians warns “do not cure evil with evil”.[3]

The word was common in the medical writers and in the Gospels, where it is used of Jesus' healing of the sick and, figuratively, of restoring people from other ills.[7][6] Its derivatives ἰατρός (iatrós, “physician”) and ἴασις (íasis, “healing”) go back to Homer and Ionic prose.[2]
