Daft name for a woman (5)
I believe the answer is:
dotty
I believe this clue is a triple definition!
'daft' is the first definition.
('dotty' can be a synonym of 'daft')
'name' is the second definition.
'for' acts as a link.
'a woman' is the third definition.
(Other definitions for dotty that I've seen before include "Bonkers; speckled" , "Barking" , "Slightly crazy" , "Silly; crazy" , "Eccentric, slightly mad" .)
