In Persian, the word Qadaqan (q is an uvular stop consonant, i.e. having the same place of articulation as the French r) means "emphasis" and "illegal", in some Persian dictionaries it is mentioned as a Turkic word, and some say it's Mongolian and in a linguistics book I read it's native Persian. I want someone who knows Turkic or Mongolian to tell me is this word from that origins?
The modern Persian word pronounced /γadaγan/ means “prohibition” and the like; it is spelt both as غدغن and as قدغن. It can hardly be a native Persian word. I have searched for it in Clauson’s “Etymological dictionary of pre-thirteenth-century Turkish” (do note that Clauson uses “Turkish” to include all Turkic languages), as well as in several dictionaries of modern (Anatolian) Turkish, but found nothing.
It occurs, however, in the Urmi dialect of Neo-Aramaic. In his dictionary of that language Geoffrey Khan derives it via Azeri from Mongolian qadagala “to keep in confinement”.
