The word Shemiran or Shemran is the arabized form of the word Chamran consisted of two parts: "cham" (meaning "cold" in Avestan; "zama" or "zem") + "ran" (meaning "slope"). In fact "shemran" means "the cold place" or "the cold slope"
It is common in the Iranian languages that the letter "z" changes to letter "ch", For example in Persian the word "ruz" or "rooz" (day), from Middle Persian "roch", is still "roch" in Balochi language and "roj" in Kurdish. Another example is the word "zemestan" (winter) consisted of two parts: "zem" (cold) + "estan" or "istan" (being, or existence), which sometimes can be seen in Persian Literature and common usage as "chamestan" or "chemestan".
