Cancel cleaning process (5)
I believe the answer is:
scrub
This could be a double definition.
'cancel' is the first definition.
(scrub can mean to cancel or erase)
'cleaning process' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for scrub that I've seen before include "Rub hard with a brush" , "Axe" , "Undergrowth" , "Scour - stunted trees" , "Rub hard - low vegetation" .)
