Harry essentially snubbed England after losing almost everything (9)
I believe the answer is:
persecute
'harry' is the definition.
(I know that persecute is a more specific form of bedevil)
'essentially snubbed england after losing almost everything' is the wordplay.
I cannot really understand how this works, but
'essentially' could be 'perse' (I've seen this in another clue) and 'perse' is located in the answer.
'snubbed' could be 'cut' (to snub something can be to cut its end off) and 'cut' is found in the answer.
'england' could be 'e' (short for England) and 'e' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for persecute that I've seen before include "Oppress, cause to suffer" , "Harass for reasons of politics, religion etc" , "Oppress, harass" , "Dog" , "Persistently harass" .)
