Swagger of a daughter in good show! (7)
I believe the answer is:
bravado
'swagger' is the definition.
(thesaurus)
'a daughter in good show' is the wordplay.
'a daughter' becomes 'ad' (I've seen this in other clues).
'in' means one lot of letters goes inside another.
'good show' becomes 'bravo'.
'ad' inserted within 'bravo' is 'BRAVADO'.
'of' is the link.
(Other definitions for bravado that I've seen before include "Boastfulness" , "Daring to impress" , "showing off" , "Boastful swagger" , "Swaggering confidence" .)
