Konkan
The origins of Konkani language from the historic viewpoint are very interesting. The Aryans who migrated to India familiarized themselves in North India and established several languages based on the local influence. Depending on their geographical dispersion you can categorize two distinct groups. Punjabi, Rajastani, Gujarati, and Hindi evolved from Prakrit of Magadha and Sindhi Maithili, Assamese, Bengali originated from Shouraseni Prakrit. Konkani belongs to the second group, and hence some scholars regard Bengali or Assamese as the mother of Konkani language. However, in reality the three are siblings of the same (now nonexistent) intermediary parent language. The arguments on the matter continue to generate a lot of response among linguists. Some historians argue that it was the language of Aryans who came further south to the Konkan, and hence the name Konkani. The most important point to note here is that Konkani is first seen in the Konkan area. Early adopters used the Brahmi script, but eventually due to the local influence, Nagari (a.k.a. Devanagari) was used for the benefit of much larger audience
