Looked at some grey edifices (4)
I believe the answer is:
eyed
'looked at' is the definition.
(I've seen this before)
'some grey edifices' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'EYED' is hidden in the letters of 'grey edifices'.
(Other definitions for eyed that I've seen before include "Saw" , "Spotted" , "Closely observed" , "Viewed" , "Vegetable" .)
