The gander will fly off (6)
I believe the answer is:
glance
This clue might be a double definition.
'the gander' is the first definition.
(I've seen this before)
'fly off' is the second definition.
(I've seen this before)
'will' is the link.
This may not be correct. It may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for glance that I've seen before include "Momentary look" , "Batting stroke" , "Skim" , "Peek" , "deflection" .)
