Look to flick it off the legs (6)
I believe the answer is:
glance
'look' is the definition.
(I know that glance is a kind of look)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for glance that I've seen before include "Glimpse" , "Stroke - gander" , "black shiny stuff" , "Butcher" , "Batsman's stroke" .)
