Feeling of anxiety in business? (7)
I believe the answer is:
concern
I believe this clue is a triple definition!
'feeling' is the first definition.
(concern is a kind of feeling)
'of' acts as a link.
'anxiety' is the second definition.
(concern is a kind of anxiety)
'in' acts as a link.
'business?' is the third definition.
(business is a kind of concern)
(Other definitions for concern that I've seen before include "Relate to; anxiety" , "Affair" , "Disquiet" , "Cause of anxiety" , "Have something to do with" .)
