"Arabian mate" meaning in English

{
  "etymology_text": "Possibly named such because the pattern was also possible in shatranj, the Middle Eastern predecessor to chess which included rooks and knights but had many other differences.\nAccording to various sources, the mate is described in an eighth century Arabic manuscript, but this claim could not be substantiated. The pattern, however, does appear as a solution to a position presented in an anonymous Arabic-language manuscript that was copied in 1257 (original source of material unknown).",
