Puzzle concerning the raising of a subscription? (5)
I believe the answer is:
rebus
'puzzle' is the definition.
(type of visual puzzle)
'concerning the raising of a subscription?' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'the raising of a subscription?' becomes 'bus' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
're'+'bus'='REBUS'
Can you help me to learn more?
(Other definitions for rebus that I've seen before include "solver?" , "Puzzling symbols, etc" , "Picture-puzzle" , "Visual pun" , "Ian Rankin's Scottish detective" .)
