Learned borrowing from Late Latin prognōsis (“forecast, prediction; forecast of the course and outcome of a disease”), itself borrowed from Ancient Greek πρόγνωσις (prógnōsis, “forecast of the course and outcome of a disease; (Koine) foreknowledge, perceiving beforehand, prediction”), from προ- (pro-, prefix meaning ‘before; beforehand’) + γνῶσῐς (gnôsĭs, “inquiry, investigation; knowledge”). The plural prognoses is a learned borrowing from Late Latin prognōsēs. Cognates * Middle French prognosie (“forecast, prediction”) (modern French prognosie (obsolete), prognose (“forecast of the course and outcome of a disease”)) * Sanskrit प्रज्ञा (prajñā, “intelligence, wisdom; judgment; knowledge”)
