Where one's heading to India, sent abroad (11)
I believe the answer is:
destination
'where one's heading' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'to india sent abroad' is the wordplay.
'abroad' indicates an anagram.
'to'+'india'+'sent'='toindiasent'
'toindiasent' with letters rearranged gives 'DESTINATION'.
Can you help me to learn more?
(Other definitions for destination that I've seen before include "terminal" , "Journey's end" , "End of journey" , "Final goal" , "Place to which one is travelling" .)
