Where it originally was (2,4)
I believe the answer is:
in situ
'where it originally was' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for in situ that I've seen before include "Appropriately positioned" , "In the proper position" , "American lift" , "In its original place, in Latin" , "Appropriately located" .)
