Advanced celebrity houses left burning (6)
I believe the answer is:
aflame
'burning' is the definition.
(thesaurus)
'advanced celebrity houses left' is the wordplay.
'advanced' becomes 'a'.
'celebrity' becomes 'fame' ('fame' can be a synonym of 'celebrity'**).
'houses' indicates putting letters inside.
'left' becomes 'l' (common abbreviation).
'fame' enclosing 'l' is 'flame'.
'a'+'flame'='AFLAME'
(Other definitions for aflame that I've seen before include "On fire" , "fired up?" , "Ablaze" , "Deeply aroused" , "Ma, flea could be burning" .)
