Wailing women? (6)
I believe the answer is:
sirens
'women?' is the definition.
(siren is a kind of woman)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for sirens that I've seen before include "Warning devices with loud wailing noise" , "Loud wailing warnings sounds" , "Devices that warn with a loud wailing noise" , "Loud warning signals" , "Alarm whistles or temptresses of sailors" .)
