Scatter seeds around garden boundary for bird (7)
I believe the answer is:
swallow
'for bird' is the definition.
(swallow is a kind of bird)
'scatter seeds around garden boundary' is the wordplay.
'scatter seeds' becomes 'sow' (I've seen this in another clue).
'around' indicates putting letters inside.
'garden boundary' becomes 'wall' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sow' enclosing 'wall' is 'SWALLOW'.
Can you help me to learn more?
(Other definitions for swallow that I've seen before include "Bird - gulp down" , "Eat - bird - believe" , "Small migratory bird with forked tail" , "Buy < and consume" , "Fall for; bird" .)
