Load of laundry (4)
I believe the answer is:
wash
'load of laundry' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wash that I've seen before include "shower" , "put on thin coat" , "Clean; thin coat of paint" , "The ----, inlet of the North Sea" , "Laundry" .)
