Father close to an alluring woman (5)
I believe the answer is:
siren
'alluring woman' is the definition.
(I've seen this before)
'father close to an' is the wordplay.
'father' becomes 'sire' ('sire' can be a synonym of 'father').
'close to' says to take the final letters (the close/ending of).
The last letter of 'an' is 'n'.
'sire'+'n'='SIREN'
(Other definitions for siren that I've seen before include "Alarm - charming female" , "Seductive woman" , "Alarm - fascinating woman" , "Loud warning signal" , "Temptress - warning device" .)
