Cancel loser (5)
I believe the answer is:
scrub
This could be a double definition.
'cancel' is the first definition.
(I know that cancel can be written as scrub)
'loser' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
Can you help me to learn more?
(Other definitions for scrub that I've seen before include "Cancel (colloq)" , "Clean with hard brush and soapy water" , "Drop" , "Get rid of" , "Eradicate" .)
