Opponent's record movement is uncontaminated (10)
I believe the answer is:
antiseptic
'uncontaminated' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'opponent's record movement' is the wordplay.
'opponent's' becomes 'anti's' (someone opposed to something).
'record' becomes 'EP' (abbreviation for extended play record).
'movement' becomes 'tic' (an involuntary physical movement).
'antis'+'ep'+'tic'='ANTISEPTIC'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for antiseptic that I've seen before include "Clinical" , "germicide" , "Designed to counteract infection" , "Preventing growth of microorganisms" , "treatment" .)
