Male goose (6)
I believe the answer is:
gander
'male goose' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gander that I've seen before include "Male 7 across" , "Glimpse" , "'What's sauce for the goose is sauce for the . . . . . .'" , "Bird from Newfoundland airport" , "Ranged over the bird" .)
