Look furtively over in dance (4)
I believe the answer is:
reel
This clue might be a double definition.
'look furtively over in' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'dance' is the second definition.
(I know that reel is a type of square dance)
Can you help me to learn more?
(Other definitions for reel that I've seen before include "Stagger in Irish dance" , "Highland dance" , "Rock" , "A merry dance or an angler's winder" , "Dance - swim" .)
