European married in Suez, oddly (5)
I believe the answer is:
swede
'european' is the definition.
(I know that Swede is a type of european)
'married in suez oddly' is the wordplay.
'married' becomes 'wed' (wed can mean married).
'in' is an insertion indicator.
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
The alternating letters of 'suez' are 'se'.
'wed' inserted inside 'se' is 'SWEDE'.
(Other definitions for swede that I've seen before include "Scandinavian - vegetable" , "Nobel for one" , "Sort of turnip - one from Scandinavia?" , "Cattle fodder" , "Scandinavian; root veg." .)
