Final Four game (4)
I believe the answer is:
semi
'final four game' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for semi that I've seen before include "Prefix denoting half" , "Type of house (UK) - type of truck (US)" , "The last but one round" , "House linked to another" , "House sharing a wall" .)
