Nationality of woman and husband (5)
I believe the answer is:
irish
'nationality' is the definition.
(Irish is an example)
'woman and husband' is the wordplay.
'woman' becomes 'iris' (woman's name).
'and' is a charade indicator (letters next to each other).
'husband' becomes 'h'.
'iris'+'h'='IRISH'
'of' is the link.
(Other definitions for irish that I've seen before include "Hi, Sir, become a national" , "of Hibernia" , "Nationality" , "Hibernian -- breed of 4" , "From Eire" .)
