Sample from brochures -- is tan cedarwood used for protection? (10)
I believe the answer is:
resistance
'for protection?' is the definition.
(thesaurus)
'sample from brochures is tan cedarwood' is the wordplay.
'sample' says the answer is hidden in the clue (I've seen this in other clues).
'RESISTANCE' is hidden within 'from brochures is tan cedarwood'.
'used' is the link.
(Other definitions for resistance that I've seen before include "defiance" , "Rebellious group" , "Withstanding" , "underground movement" , "fighters in wartime" .)
