Cancel Supreme Court impediment (5)
I believe the answer is:
scrub
'cancel' is the definition.
(scrub can mean to cancel or erase)
'supreme court impediment' is the wordplay.
'supreme court' becomes 'sc' (this could be a standard abbreviation I've not previously seen).
'impediment' becomes 'rub' (rub is a kind of impediment).
'sc'+'rub'='SCRUB'
Can you help me to learn more?
(Other definitions for scrub that I've seen before include "Powerful wash" , "Scour - stunted trees" , "Eliminate" , "Brush dirt off - delete - stunted vegetation" , "Take out - clean" .)
