Stimulating call after fuss (8)
I believe the answer is:
stirring
'stimulating' is the definition.
('stir' can be a synonym of 'stimulate')
'call after fuss' is the wordplay.
I cannot quite see how this works, but
'call' could be 'ring' (telephone call) and 'ring' is located in the answer.
'fuss' could be 'stir' (synonyms) and 'stir' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for stirring that I've seen before include "Exciting" , "Arousing strong feeling" , "causing trouble" , "Inspiring" , "Heady" .)
