Unprepared for possible war (3)
I believe the answer is:
raw
'unprepared' is the definition.
(I've seen this in another clue)
'possible war' is the wordplay.
'war' can be anagrammed to 'RAW'.
However, I'm not clear how the anagram is indicated.
'for' is the link.
Can you help me to learn more?
(Other definitions for raw that I've seen before include "Unrefined" , "not manufactured" , "Uncooked or unsophisticated" , "Unpleasantly cold and damp" , "Uncooked; immature" .)
