The digs may be seen (7)
I believe the answer is:
sighted
'seen' is the definition.
(I've seen this before)
'the digs may be' is the wordplay.
'may be' indicates anagramming the letters.
'the'+'digs'='thedigs'
'thedigs' with letters rearranged gives 'SIGHTED'.
(Other definitions for sighted that I've seen before include "Viewers are" , "Seen" , "able to observe" , "Saw, observed" , "Espied" .)
