Joining figure that is prancing in fur coats (7)
I believe the answer is:
unifier
'joining figure that is prancing in fur coats' is the definition.
The definition suggests a singular noun which matches the answer.
'joining figure that is' is the wordplay.
I cannot really see how this works, but
'that is' could be 'ie' ('i.e.' can be a synonym of 'that is') and 'ie' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for unifier that I've seen before include "One bringing together" , "Binder" , "Type who joins in" , "It makes one" , "One who amalgamates, consolidator" .)
