Further afield, in ancient Iran, a fortified wooden settlement was called a "gerd", or "certa", which also means garden (as in the suffix "-certa" in the names of various ancient Iranian cities; e.g., "Hunoracerta"). The Persian word evolved into "jerd" under later Arab influence. Burugerd or Borujerd is a city in the west of Iran. The Indian suffix "-garh", meaning a fort in Hindi, Sanskrit, and other Indo-Iranian languages, appears in many Indian place names. Given that both Slavic and Indo-Iranian are sub-branches of Indo-European and that there are numerous similarities between Slavic and Sanskrit vocabulary, it is plausible that "garh" and "gord" are related. However, this is strongly contradicted by the phoneme /g/ in Indo-Iranian, which cannot be a reflex of the Indo-European palatovelar /*ǵ/.
