Land at the end of a passage? (5)
I believe the answer is:
india
'land' is the definition.
(I know that India is a Asian country)
'at the end of a passage?' is the wordplay.
'at' becomes 'in' (synonymous in some cases - eg at school, in school).
'the end of a passage?' becomes 'dia' (I can't explain this - if you can you should believe this answer much more).
'in'+'dia'='INDIA'
(Other definitions for india that I've seen before include "vast country" , "A Passage to - (E.M. Forster)" , "Major sub-continent of Asia" , "Big country" , "Comms code for I" .)
