Abandon insignificant drudge (5)
I believe the answer is:
scrub
This clue might be a double definition.
'abandon' is the first definition.
(scrub can mean to remove or delete)
'insignificant drudge' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for scrub that I've seen before include "Curbs (anag.)" , "remove cosmetic" , "Area of dense stunted vegetation" , "Wash with a brush" , "Clean with hard brush and soapy water" .)
