Something to wear for a pound (3)
I believe the answer is:
alb
'something to wear' is the definition.
I can't judge whether this defines the answer.
'a pound' is the wordplay.
'pound' becomes 'lb' (synonyms).
'a'+'lb'='ALB'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for alb that I've seen before include "Without hindrance" , "Long white church vestment" , "Long white robe worn by Christian priest" , "clerical belongings" , "Long white robe worn by proest" .)
