Pronunciation

  • 5th-century BC Attic: /tʰe.ra.pěː.aː/[1]
  • 4th-century AD Koine: /θe.raˈpi.a/[1]
  • 10th-century Byzantine: /θe.raˈpi.a/[1]

Forms

θερᾰπείᾱ (therapeíā) f (genitive θερᾰπείᾱς); first declension[1] Ionic θεραπηίη (also θεραπείη in Hippocrates).[2][3]

Etymology

It is formed from Ancient Greek θεραπεύω (therapeúō, “to serve; to treat”) + -ία (-ía).[1][3][4] The verb comes from θεράπων (therápōn, “attendant”), a word Beekes considers Pre-Greek.[4]

Earliest recorded meaning

It appears in the 5th century BC, in Euripides of service paid to the gods and in Thucydides of paying court to someone.[2][5]

Semantic evolution

Its first sense is service: worship of the gods, respect for parents, devotion to a lover, and court paid to the powerful, which could turn into flattery.[3][2] Care for oneself or others led to care of the sick, and Antiphon and the Hippocratic writers use it of medical or surgical treatment, as Plato does of cures by cautery.[3][2] It also meant the nurture of children, the training of animals, the cultivation of land, the upkeep of a house and, concretely, adornment, and a body of servants.[3]

In the Koine papyri and the New Testament it is treatment and healing, and also the household servants of a master.[6] Medieval Greek kept it, and Modern Greek θεραπεία (therapeía), “treatment, cure”, is a learned form of it.[7][8] Through Modern Latin therapia it gave English therapy in 1846.[9]
