Male newlywed, an islander (9)
I believe the answer is:
hebridean
'islander' is the definition.
(I've seen this before)
'male newlywed an' is the wordplay.
'male' becomes 'he'.
'newlywed' becomes 'bride' (bride is a kind of newlywed).
'he'+'bride'+'an'='HEBRIDEAN'
(Other definitions for hebridean that I've seen before include "Scot!" , "from the Western Isles" , "from Scottish island" , "Scottish islander" , "from Harris, for example" .)
