Ado, bother (4)
I believe the answer is:
fuss
This clue is a double definition.
'ado' is the first definition.
(I know that ado can be written as fuss)
'bother' is the second definition.
(I know that bother can be written as fuss)
(Other definitions for fuss that I've seen before include "Protest -- excitement" , "trouble" , "Unnecessary excitement or bother" , "Excessive activity" , "Commotion; ado" .)
