Broken hearts not in this direction (5-4)
I believe the answer is:
north-east
'this direction' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'broken hearts not in' is the wordplay.
'broken' is an anagram indicator.
'in' is an insertion indicator.
'hearts' with letters rearranged gives 'rtheas'.
'rtheas' going within 'not' is 'NORTH-EAST'.
Can you help me to learn more?
(Another definition for north-east that I've seen is " Top right region on a map".)
