Not all of these correspond perfectly to an Outer IA grouping (e.g. some Rajasthani lects and Haryanvi continue OIA "-(i)tavya") but do constitute shared innovation. For Southworth, Outer encompasses Bengali, Assamese, Odia, Bihari, Marathi, Konkani, Gujarati, and Sindhi. George Cardona and Dhanesh Jain responded, "I think it fair to say that these conclusions are not sufficiently backed up by detailed facts about the chronology of changes to merit their being accepted as established"; that is to say, for many of the supposed differences between Inner and Outer, there is no clear historical evidence attesting that they reflect OIA divisions and not more recent changes or areal diffusions.
