Passage into India is legendary (5)
I believe the answer is:
aisle
'passage' is the definition.
(aisle is a kind of passage)
'into india is legendary' is the wordplay.
'into' indicates the answer is hidden within the clue.
'AISLE' can be found hidden inside 'india is legendary'.
(Other definitions for aisle that I've seen before include "Supermarket passageway" , "Supermarket feature" , "Passageway between blocks of seats" , "that would-be bride hopes to make it up!" , "Divide in a church" .)
