  Though some archaeologists claim that some 10th-century texts were in Bengali, it is not certain whether they represent a differentiated language or whether they represent a stage when Eastern Indo-Aryan languages were differentiating. The local Apabhraṃśa of the eastern subcontinent, Purbi Apabhraṃśa or Abahatta (lit. 'meaningless sounds'), eventually evolved into regional dialects, which in turn formed three groups, the Bengali–Assamese languages, the Bihari languages, and the Odia language.
  
  The language was not static: different varieties coexisted and authors often wrote in multiple dialects in this period. For example, Ardhamagadhi is believed to have evolved into Abahatta around the 6th century, which competed with the ancestor of Bengali for some time. The ancestor of Bengali was the language of the Pala Empire and the Sena dynasty.
