Dance and drink with bachelor (5)
I believe the answer is:
rumba
'dance' is the definition.
(rumba is a type of dance)
'drink with bachelor' is the wordplay.
'drink' becomes 'rum' (rum is a kind of drink).
'with' means one lot of letters go next to another.
'bachelor' becomes 'BA' (Bachelor of Arts).
'rum'+'ba'='RUMBA'
'and' acts as a link.
(Other definitions for rumba that I've seen before include "Burma (anag)" , "Lively Cuban dance" , "music one can dance to" , "number of steps" , "What to perform" .)
