Pronunciation

  • Classical: [karˈdi.a.kʊs][1]
  • Ecclesiastical: [karˈdiː.a.kus][1]

Forms

cardiacus (feminine cardiaca, neuter cardiacum); first/second-declension adjective[1]

Etymology

It is borrowed from Ancient Greek καρδιακός (kardiakós, “of the heart”),[2][1][3] from καρδία (kardía, “heart; stomach”).[4] Köbler traces the Greek noun to Proto-Indo-European *ḱerd- (“heart”).[4]

Earliest recorded meaning

Köbler dates the noun from Cicero,[4] who writes that this should perhaps not be attributed to sufferers from the disorder either, haud sciō an nec cardiacīs hoc tribuendum sit.[2]

Semantic evolution

It meant of or affecting the heart or stomach;[2][3] morbus cardiacus, in Celsus and Pliny the Elder, was a disorder of the heart or stomach, perhaps heartburn.[2][3] A person with this disorder was cardiacus, and the masculine was used as a noun for such a sufferer: Horace says that a sick man is not cardiacus, Juvenal has a man who would never send a cup to a friend with the disorder, and Seneca says that drinking and sweating are a cardiac patient's life.[2][3] Vegetius uses it of horses and cattle.[3] Isidore has a feminine noun cardiacē for the disease.[5]

Medieval Latin used it for one suffering from heart disease,[6] and British medieval writers for the heart, for cardiac fever and for heart disease generally.[7]
