Troupe putting daughter in best role, clap wildly (5,2,6)
I believe the answer is:
corps de ballet
'troupe' is the definition.
(thesaurus)
'daughter in best role clap wildly' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'in' means one lot of letters goes inside another.
'wildly' indicates an anagram.
'best'+'role'+'clap'='bestroleclap'
'bestroleclap' with letters rearranged gives 'corpseballet'.
'd' placed inside 'corpseballet' is 'CORPS DE BALLET'.
'putting' is the link.
(Other definitions for corps de ballet that I've seen before include "dance troupe" , "dancers" , "Dancing troupe" .)
