Top drawer ladies number sounded warning (10)
I believe the answer is:
noblewomen
'top drawer ladies' is the definition.
'noblewomen' can be an answer for 'ladies' ('noblewoman' can be a synonym of 'lady'). I'm unsure of the 'top drawer' bit.
'number sounded warning' is the wordplay.
'number' becomes 'no' (abbreviation).
'sounded' becomes 'blew' (blowing is a kind of sounding).
'warning' becomes 'omen' (omen can mean a warning or sign of the future).
'no'+'blew'+'omen'='NOBLEWOMEN'
Can you help me to learn more?
(Other definitions for noblewomen that I've seen before include "Peeresses" , "ladies" , "Aristocrats" , "some of the aristocracy" .)
