Important lady found in wreckage of Nazi car (7)
I believe the answer is:
czarina
'important lady' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'wreckage of nazi car' is the wordplay.
'wreckage of' is an anagram indicator (I've seen this in other clues).
'nazi'+'car'='nazicar'
'nazicar' anagrammed gives 'CZARINA'.
'found in' acts as a link.
Can you help me to learn more?
(Other definitions for czarina that I've seen before include "Russian empress" , "In a Z Car? (anag)" .)
