Sound warning for a temptress? (5)
I believe the answer is:
siren
This clue could be a double definition.
'sound warning' is the first definition.
'siren' can be an answer for 'warning' (I've seen this before). I'm not sure about the 'sound' bit.
'temptress?' is the second definition.
(I know that temptress can be written as siren)
'for a' is the link.
Can you help me to learn more?
(Other definitions for siren that I've seen before include "Temptress - makes a loud noise!" , "'Delilah!'" , "Loud warning signal" , "Loud whistle or dangerous woman" , "Alarm; temptress" .)
