Take wicket, then settle down in ground in final season (6)
I believe the answer is:
winter
'final season' is the definition.
(last season of the year)
'take wicket then settle down in ground' is the wordplay.
'take wicket then' becomes 'w' (I can't explain this - if you can you should give a lot more credence to this answer).
'settle down in ground' becomes 'inter' (as in interring a body).
'w'+'inter'='WINTER'
'in' is the link.
Can you help me to learn more?
(Other definitions for winter that I've seen before include "Cold season" , "Cold period" , "period of freeze?" , "'If . . . . . . comes, can spring be far behind?'" , "period of discontent?" .)
