Take exception to being ordered to leave again (6)
I believe the answer is:
resent
'take exception to' is the definition.
(I've seen this before)
'ordered to leave again' is the wordplay.
'ordered' becomes 'sent'.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'leave again' becomes 're' (I can't explain this - if you can you should give a lot more credence to this answer).
'sent' after 're' is 'RESENT'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for resent that I've seen before include "being put in post again" , "Take offence at" , "Consider (something) to be an affront" , "Find objectionable" , "Take exception to" .)
