Enlarge fuzzy detail (6)
I believe the answer is:
dilate
'enlarge' is the definition.
(I've seen this before)
'fuzzy detail' is the wordplay.
'fuzzy' indicates an anagram.
'detail' is an anagram of 'DILATE'.
(Other definitions for dilate that I've seen before include "Widen as eyes may" , "Make or become wider" , "Expand - talk at length" , "Swell" , "Make wider or larger" .)
