Where art lover may be, catching the setter's hint (8)
I believe the answer is:
intimate
This clue could be a double definition.
'where art lover may be catching the setter's' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'hint' is the second definition.
(I know that intimate is a more specific form of the action hint)
(Other definitions for intimate that I've seen before include "Make known" , "Infer; personal" , "Close acquaintance" , "cosy" , "Private and personal like close acquaintanceship" .)
