Burn wayward lazy daughter? Wild! (9)
I believe the answer is:
unbridled
'wild' is the definition.
(thesaurus)
'burn wayward lazy daughter?' is the wordplay.
'wayward' is an anagram indicator (wayward means out of control or chaotic).
'lazy' becomes 'idle' (similar in meaning).
'daughter?' becomes 'd' (genealogical abbreviation).
'burn' with letters rearranged gives 'unbr'.
'unbr'+'idle'+'d'='UNBRIDLED'
(Other definitions for unbridled that I've seen before include "Without constraint" , "Fully and freely" , "Without restraint, as horse may be" , "Not restrained or controlled" , "Unrestrained" .)
