Down-to-earth soldier gets married in Italian city (5)
I believe the answer is:
parma
'italian city' is the definition.
(I've seen this in another clue)
'down-to-earth soldier gets married' is the wordplay.
'down-to-earth soldier' becomes 'para' (paratrooper).
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'para' enclosing 'm' is 'PARMA'.
'in' is the link.
(Other definitions for parma that I've seen before include "Italian city known for ham and violets" , "Here in Italy" , "Italian city noted for ham" , "Italian city famous for cheese and ham" , "Italian city producing cured ham" .)
