Feeling created by European proposal (7)
I believe the answer is:
emotion
'feeling' is the definition.
(I know that emotion is a type of feeling)
'by european proposal' is the wordplay.
'by' means one lot of letters go next to another.
'european' becomes 'E' (abbreviation e.g. EU).
'proposal' becomes 'motion' (proposal at a meeting).
'e'+'motion' is 'EMOTION'.
'created' is the link.
(Other definitions for emotion that I've seen before include "Mental agitation" , "Mental feeling" , "Agitation of mind" , "Strong desire" , "Anger, perhaps" .)
