“ The Kotas speak a mixture of Tamil and Kanarese, and speak Tamil without the foreign accent which is noticeable in the case of the Badagas and Todas. According to orthodox Kota views, a settlement should consist of three streets or kēris, in one of which the Terkāran or Dēvādi, and in the other two the Munthakannāns or Pūjāris live. At Kotagiri the three streets are named Kīlkēri, Nadukēri, and Mēlkēri, or lower, central, and upper street. People belonging to the same kēri may not intermarry, as they are supposed to belong to the same family, and intermarriage would be distasteful. ”
