Dance in state capital (10)
I believe the answer is:
charleston
I believe this clue is a double definition.
'dance' is the first definition.
(I know that Charleston is a type of ballroom dance)
'state capital' is the second definition.
(state capital of West Virginia)
'in' acts as a link.
(Other definitions for charleston that I've seen before include "Dance making" , "Nineteen twenties dance" , "Lively dance - then carols (anag)" , "Lively 1920s' dance" , "US city - 1920s' dance" .)
