Motive to get fresh start in spring, say (6)

I believe the answer is:
season
'spring say' is the definition.
(spring is a season)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for season that I've seen before include "Salt, maybe" , "Eg, summer" , "eg Winter" , "Particular time (for activity, conditions etc)" , "Spring, say" .)
