Turnover from two seasons say (10)
I believe the answer is:
somersault
'turnover' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for somersault that I've seen before include "Feat of acrobatics" , "Move acrobatically" , "Perform acrobatic feat" , "policy switch" , "Acrobatic movement" .)
