Fancy, whim (7)
I believe this clue is a double definition.
'fancy' is the first definition.
(both can mean an idea or whim)
'whim' is the second definition.
(I know that whim can be written as notion)
(Other definitions for notion that I've seen before include "Vague idea or opinion" , "Vague or fanciful idea" , "clue" , "Concept, belief" , "Idea or fancy" .)
