Cunningly see and grasp warnings (8)
I believe the answer is:
presages
'warnings' is the definition.
(I've seen this in another clue)
'cunningly see and grasp' is the wordplay.
'cunningly' indicates an anagram (a cunning or tricky form of the letters).
'and' is a charade indicator (letters next to each other).
'see' put after 'grasp' is 'graspsee'.
'graspsee' is an anagram of 'PRESAGES'.
(Other definitions for presages that I've seen before include "Forecasts" , "Augurs, bodes" , "Foreshadows, is advance sign of" , "Foreshadows in press age" .)
