One of the Pointer Sisters (5)
I believe the answer is:
anita
'one of the pointer sisters' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anita that I've seen before include "Woman" , "lady" , "-- Brookner, English novelist" , "girl produced" , "- Loos (Gentlemen Prefer Blondes)" .)
