Foretell or forecast (7)
I believe the answer is:
predict
I believe this clue is a double definition.
'foretell' is the first definition.
(I know that foretell can be written as predict)
'forecast' is the second definition.
(I know that forecast is a more specific form of the action predict)
(Other definitions for predict that I've seen before include "Divine" , "Forecast" , "Prophesy - portend" , "Foresee" , "Estimate consequence of" .)
