About revolutionary's secret stock (5)
I believe the answer is:
cache
'secret stock' is the definition.
'cache' can be an answer for 'stock' (cache is a kind of stock). I am unsure of the 'secret' bit.
'about revolutionary's' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa').
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'ca'+'che'='CACHE'
Can you help me to learn more?
(Other definitions for cache that I've seen before include "Nest egg" , "Hiding place for treasure etc" , "what things could be stored in" , "memory" , "Secret hiding place" .)
