Wounded eagle in descent (7)
I believe the answer is:
lineage
'descent' is the definition.
(I know that descent can be written as lineage)
'wounded eagle in' is the wordplay.
'wounded' is an anagram indicator (I've seen this in other clues).
'eagle'+'in'='eaglein'
'eaglein' anagrammed gives 'LINEAGE'.
(Other definitions for lineage that I've seen before include "Family descent" , "Ancestry, sequence of descendants" , "Descent from ancestors" , "Genealogy" , "The strain" .)
