Dance partner for Dot often? (5)
I believe the answer is:
polka
'dance' is the definition.
(I know that dance is a is a more specific form of the action of polka)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for polka that I've seen before include "a merry dance?" , "Take rapid steps" , "Lively dance of Bohemian origin" , "An originally Bohemian dance" , "Dance in fast time with three steps and a hop" .)
