Simple map including India (5)
I believe the answer is:
plain
'simple' is the definition.
(associated in meaning)
'map including india' is the wordplay.
'map' becomes 'plan' (I've seen this in another clue).
'including' is an insertion indicator.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'plan' enclosing 'i' is 'PLAIN'.
(Other definitions for plain that I've seen before include "Evident; not fancy" , "Sheer; frank" , "Obvious - ordinary" , "not attractive" , "Unembellished" .)
