Time of revolution (7)
'time of revolution' is the definition.
(as in the 1917 October Revolution in Russia)
'time of' is the wordplay.
I cannot quite understand how this works, but
'time' could be 't' (abbreviation) and 't' is found in the answer.
'of' could be 'o' and 'o' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for october that I've seen before include "Eighth month on the Roman calendar, originally" , "Revolutionary period" , "21st = Trafalgar Day" , "thirty-one days" , "Time for revolution" .)
'time of revolution?' is the definition.
(I've seen this in another clue)
This is all the clue.
