Fisherman's dance? (4)
I believe the answer is:
reel
This clue might be a double definition.
'fisherman's' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'dance?' is the second definition.
(reel is a kind of dance)
(Other definitions for reel that I've seen before include "Dance - swim" , "Highland dance" , "Dance; feel giddy" , "Stagger with rod winder" , "Lurch; spool" .)
