A party always means fuss (3)
I believe the answer is:
ado
'fuss' is the definition.
(synonyms)
'a party always' is the wordplay.
'party always' becomes 'do' (do is a kind of party. I am not sure about the 'always' bit.).
'a'+'do'='ADO'
'means' acts as a link.
Can you help me to learn more?
(Other definitions for ado that I've seen before include "Busy activity, trouble" , "Goings-on" , "Hoo-ha" , "Shakespeare: 'Much ... About Nothing'(3) ()" , "Fuss or bustle" .)
