Dance with zest before ball (5)
I believe the answer is:
tango
'dance' is the definition.
(Tango is a dance)
'zest before ball' is the wordplay.
'zest' becomes 'tang' (synonyms).
'before' is a charade indicator (letters next to each other).
'ball' becomes 'o' (O looks like a ball).
'tang'+'o'='TANGO'
'with' is the link.
(Other definitions for tango that I've seen before include "Last - in Paris (film)" , "Dance; letter T" , "Latin American dance takes two to do it" , "Tonga (anag.)" , "Dance music" .)
