Are such materials for making war? (3)
I believe the answer is:
raw
'are such materials' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives occasionally mean the same thing.
'making war?' is the wordplay.
'making' is an anagram indicator.
'war' is an anagram of 'RAW'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for raw that I've seen before include "Abraded" , "Inexperienced in war (3)" , "Unrefined" , "Untried (of recruit) - uncooked (of meat)" , "Like a recruit" .)
