Notice the hole and fuss… (3)
I believe the answer is:
ado
'fuss' is the definition.
('ado' can be a synonym of 'fuss')
'notice the hole' is the wordplay.
'notice' becomes 'ad'.
'the hole' becomes 'o'.
'ad'+'o'='ADO'
'and' acts as a link.
(Other definitions for ado that I've seen before include "stir" , "Busy activity, trouble" , "Goings-on" , "excitement" , "Fuss, trouble" .)
