Strident daughter in tirade after party (10)
I believe the answer is:
discordant
'strident' is the definition.
(thesaurus)
'daughter in tirade after party' is the wordplay.
'daughter' becomes 'd'.
'in' is an insertion indicator.
'tirade' becomes 'rant' (I've seen this before).
'after' says to put letters next to each other.
'party' becomes 'disco' (I've seen this before**).
'd' inserted inside 'rant' is 'rdant'.
'rdant' put after 'disco' is 'DISCORDANT'.
(Other definitions for discordant that I've seen before include "At variance" , "Raucous" , "Lacking harmony; conflicting" , "off-key" .)
