Little bets on quivers (8)
I believe the answer is:
flutters
'quivers' is the definition.
(I know this)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for flutters that I've seen before include "bats" , "Small bets; flaps" , "Moves like a butterfly, towardsthe bookies?" , "23 [BETTER] has" .)
