Large flock coming back through pasture see gate (5)
I believe the answer is:
geese
'large flock coming back through pasture see gate' is the definition.
I can't tell whether this defines the answer.
'back through pasture see gate' is the wordplay.
'back' says the letters should be written backwards.
'through' indicates the answer is hidden within the clue.
'eseeg' is hidden in the letters of 'pasture see gate'.
'eseeg' back-to-front is 'GEESE'.
Can you help me to learn more?
(Other definitions for geese that I've seen before include "Long-necked, migratory aquatic birds" , "Birds that fly in a skein" , "Six of these are 'a-laying' on 31 December" , "Birds; silly people" , "Protectors of city" .)
