Obvious intention to tour India (5)
I believe the answer is:
plain
'obvious' is the definition.
(similar in meaning)
'intention to tour india' is the wordplay.
'intention' becomes 'plan' (I've seen this in another clue).
'to tour' indicates putting letters inside (to tour can mean to go around).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'plan' enclosing 'i' is 'PLAIN'.
(Other definitions for plain that I've seen before include "Not elaborate; clear" , "Unattractive - flat" , "not attractive" , "Simply" , "Simple or apparent" .)
