Take away (from) (7)
I believe the answer is:
detract
'take away from' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for detract that I've seen before include "Derogate" , "Take away (from worth)" , "Slight" , "Devaluate" , "Diminish the worth (of)" .)
