For a time, the newspapers carry warnings (8)
I believe the answer is:
presages
'warnings' is the definition.
(I've seen this in another clue)
'for a time' is the wordplay.
'for a' becomes 'pres' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'time' becomes 'ages' (ages can informally mean a long period).
'pres'+'ages'='PRESAGES'
'the newspapers carry' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for presages that I've seen before include "Augurs, bodes" , "Foreshadows, is advance sign of" , "Forecasts" , "Foreshadows in press age" .)
