Remove water (4)
I believe the answer is:
bail
'remove water' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bail that I've seen before include "may be jumped" , "Surety - part of wicket - scoop" , "Part of a wicket - legal payment" , "Remove water from -- part of wicket" , "One of two on the stumps" .)
