One's filling stuffs a turkey in European city (7)
I believe the answer is:
antwerp
'european city' is the definition.
(I've seen this before)
'one's filling stuffs a turkey' is the wordplay.
'filling' indicates the central letters (the letters which fill the word).
'stuffs' means one lot of letters goes inside another.
'turkey' becomes 'twerp' (I can't justify this - if you can you should believe this answer much more).
The central letter of 'one' is 'n'.
'a'+'twerp'='atwerp'
'n' placed within 'atwerp' is 'ANTWERP'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for antwerp that I've seen before include "North Sea port" , "Belgian port and province" , "Rent paw out in Belgium" , "European city" , "North Belgian port" .)
