Newspapers containing long-term forecasts (8)
I believe the answer is:
presages
'forecasts' is the definition.
('presage' can be a synonym of 'forecast')
'newspapers containing long-term' is the wordplay.
'newspapers' becomes 'press' (I've seen this before).
'containing' is an insertion indicator.
'long term' becomes 'age' (I've seen this before. I am not sure about the 'long' bit.).
'press' enclosing 'age' is 'PRESAGES'.
Can you help me to learn more?
(Other definitions for presages that I've seen before include "Foreshadows, is advance sign of" , "Forecasts" , "Augurs, bodes" , "Foreshadows in press age" .)
