“Well done” — welcoming a daughter’s courageous display (7)
I believe the answer is:
bravado
'courageous display' is the definition.
(a bravado is a display of courage)
'well done welcoming a daughter's' is the wordplay.
'well done' becomes 'bravo' (bravo is used to express admiration).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'daughter' becomes 'd' (genealogical abbreviation).
'a'+'d'='ad'
'bravo' going around 'ad' is 'BRAVADO'.
(Other definitions for bravado that I've seen before include "A show of boldness, may be phoney" , "Swaggering confidence" , "Impressive boldness" , "Boastful swagger" , "Showy boldness" .)
