End of season (4)
I believe the answer is:
term
I believe this clue is a double definition.
'end' is the first definition.
(I've seen this before)
'season' is the second definition.
(thesaurus)
'of' acts as a link.
(Other definitions for term that I've seen before include "Call" , "Limited period; school session" , "Name" , "Word; school session" , "Word or expression and period of time" .)
