Not a lonely part for a hooker? (5)
I believe the answer is:
talon
'a hooker?' is the definition.
(I've seen this before)
'not a lonely part' is the wordplay.
'part' indicates a hidden word.
'TALON' is hidden within 'not a lonely'.
'for' is the link.
(Other definitions for talon that I've seen before include "E.g. hawk's claw" , "part to make savage cuts" , "a gripping one" , "Bird's claw" , "Claw; undealt cards" .)
