For a time, the papers 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 can't explain this - if you can you should give a lot more credence to this answer).
'time' becomes 'ages' (ages can informally mean a long period).
'pres'+'ages'='PRESAGES'
'the papers carry' is the link.
I am not very happy about this link. Some or all of it may be part of 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" , "Foreshadows in press age" , "Forecasts" .)
