Discover, dig up (7)
I believe the answer is:
unearth
I believe this clue is a double definition.
'discover' is the first definition.
(to unearth is to discover or find)
'dig up' is the second definition.
(I've seen this before)
(Other definitions for unearth that I've seen before include "reveal" , "Bring to light, excavate" , "Expose" , "Dig up - uncover" , "Find by digging" .)
