“Singpho,” says Colonel Hannay, “signifies in the Kakhyen language ‘a man,’ and all of this race who have settled in Hookong or Assam are thus designated; the reason of their change of name I could not ascertain, but so much importance seems to be attached to it, that the Singphos, in talking of their eastern and southern neighbours, call them Kakhyens or Kakoos, and consider it an insult to be called so themselves.” (Sketch of the Singphos, or the Kakhyens of Burma, Calcutta, 1847, pp. 3–4.)
