Made indistinct (7)
I believe the answer is:
blurred
'made indistinct' is the definition.
('blur' can be a synonym of 'make indistinct')
This is the entire clue.
(Other definitions for blurred that I've seen before include "Clouded or obscured" , "Made less distinct" , "made indistinct" , "Indistinct or hazy in outline" .)
