Prognosis Is Not Just a Medical Term

With its prefix pro-, meaning "before", prognosis means basically "knowledge beforehand" of how a situation is likely to turn out. Prognosis was originally a strictly medical term, but it soon broadened to include predictions made by experts of all kinds. Thus, for example, economists are constantly offering prognoses (notice the irregular plural form) about where the economy is going, and climate scientists regularly prognosticate about how quickly the earth's atmosphere is warming.

Synonyms

• prediction
• forecast
• forecasting
• predicting
• prophecy
