Absurd pride, e.g. over European ancestry (8)
I believe the answer is:
pedigree
'ancestry' is the definition.
(pedigree is a kind of ancestry)
'absurd pride e g over european' is the wordplay.
'absurd' indicates anagramming the letters.
'over' indicates putting letters inside.
'european' becomes 'e' (abbreviation e.g. EU).
'pride'+'e'+'g'='prideeg'
'prideeg' with letters rearranged gives 'pedigre'.
'pedigre' enclosing 'e' is 'PEDIGREE'.
(Other definitions for pedigree that I've seen before include "Line of decent or ancestry" , "bloodline" , "Line of descent, family tree" , "Ancestral line" , "List of ancestors" .)
