Extra expansive (4)
I believe the answer is:
wide
This clue is a double definition.
'extra' is the first definition.
(cricket term)
'expansive' is the second definition.
(I've seen this in another clue)
(Other definitions for wide that I've seen before include "Spacious; an extra" , "Extensive" , "Of vast scope" , "Broad; cricket delivery" , "Broad - extra" .)
