Season of procession (5)
I believe the answer is:
march
This clue might be a double definition.
'season' is the first definition.
The definition and answer can be both related to time as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'procession' is the second definition.
(march is a kind of procession)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for march that I've seen before include "The month for military movement" , "Military walk; month" , "Month - proceed" , "Walk smartly" , "Colonel Bogey, for example" .)
