Extra broad (4)
I believe the answer is:
wide
This clue is a double definition.
'extra' is the first definition.
(cricket term)
'broad' is the second definition.
(I know that broad can be written as wide)
(Other definitions for wide that I've seen before include "shrewd and shifty" , "Of vast scope" , "Expansive" , "Far from the mark" , "Spacious; an extra" .)
