Marry one's husband after son reveals nationality (7)
I believe the answer is:
swedish
'nationality' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'marry one's husband after son' is the wordplay.
'marry' becomes 'wed' (synonyms).
'one's' becomes 'i's' (Roman numeral).
'husband' becomes 'h' (abbreviation).
'after' says to put letters next to each other.
'son' becomes 's' (genealogical abbreviation for son).
'wed'+'is'+'h'='wedish'
'wedish' after 's' is 'SWEDISH'.
'reveals' acts as a link.
Can you help me to learn more?
(Other definitions for swedish that I've seen before include "Soprano Jenny Lind, b. Stockholm 1798, d. Herefordshire 1887" , "From Uppsala, perhaps" , "A Scandinavian language" , "He saw Miss Degas (anag) -- Scandinavian body work" , "Nordic" .)
