European citizen’s husband tucking into fast food (7)
I believe the answer is:
burgher
'european citizen's' is the definition.
'burgher' can be an answer for 'citizen's' (I've seen this before). I'm not sure about the 'european' bit.
'husband tucking into fast food' is the wordplay.
'husband' becomes 'h' (abbreviation).
'tucking into' means one lot of letters goes inside another.
'fast food' becomes 'burger' (I've seen this before).
'h' inserted inside 'burger' is 'BURGHER'.
Can you help me to learn more?
(Other definitions for burgher that I've seen before include "Bourgeois" , "Citizen of a town or city" , "Medieval city trader" , "Townie" , "Freeman of the city" .)
