Shun bad dancing partner (7)
I believe the answer is:
husband
'partner' is the definition.
(I've seen this before)
'shun bad dancing' is the wordplay.
'dancing' indicates an anagram.
'shun'+'bad'='shunbad'
'shunbad' anagrammed gives 'HUSBAND'.
(Other definitions for husband that I've seen before include "Partner; use carefully" , "Conserve" , "Wife's partner" , "manage thriftily" , "Make careful use of" .)
