Alluring woman (5)
I believe the answer is:
siren
'alluring woman' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for siren that I've seen before include "Loud whistle for sea temptress" , "Bewitching singer,part- woman, part-bird" , "Alluring female" , "Warning device, alluring woman" , "Vamp; alarm" .)
