Soldier over in Scottish isle is put on trial (7)
I believe the answer is:
arraign
'put on trial' is the definition.
(I've seen this before)
'soldier over in scottish isle' is the wordplay.
'soldier' becomes 'gi' (government issue or general issue).
'over' shows that the letters should be reversed in order.
'in' is an insertion indicator.
'scottish isle' becomes 'arran'.
'gi' backwards is 'ig'.
'ig' put into 'arran' is 'ARRAIGN'.
'is' is the link.
(Other definitions for arraign that I've seen before include "Call before a court to answer an indictment" , "Accuse before tribunal" , "Call before court to answer criminal charge" , "Bring to trial" , "Accuse as in court" .)
