Leap east, it's a trap (7)
I believe the answer is:
springe
'it's a trap' is the definition.
(I've seen this in another clue)
'leap east' is the wordplay.
'leap' becomes 'spring' (leap can mean to spring or jump).
'east' becomes 'e' (abbreviation).
'spring'+'e'='SPRINGE'
(Other definitions for springe that I've seen before include "It ensnares" , "gin" , "Use snare" .)
