A pointed sign meaning “ladies” (5)
I believe the answer is:
women
'ladies' is the definition.
(I've seen this before)
'a pointed sign' is the wordplay.
'a pointed' becomes 'w' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sign' becomes 'omen' (omen is a kind of sign).
'w'+'omen'='WOMEN'
'meaning' is the link.
Can you help me to learn more?
(Other definitions for women that I've seen before include "Ladies" , "Adult human females" , "half of our race" .)
