Ossetic属于伊朗语系的东部分支。现今奥赛特人的语言祖先是艾伦部落，根据希腊和罗马的消息来源，他们在基督教时代的开始时从中亚移民到黑海北部和东部的土地（见ALANS，ASII）。阿兰人在中世纪早期的鼎盛时期，是西北高加索地区的一个主要人物，他们的方言在该地区广泛存在。这种语言逐渐被来自西部和北部的突厥和切尔克斯移民驱逐，现在仅限于一个相对较小的地区。有证据表明，现在的奥塞梯语区以前居住在Nakh-speaking（印古什 – 车臣，NE Caucasus）部落。以前在西北高加索地区出现的阿兰人在现代土耳其和切尔克斯地区得到了许多伊朗籍地名的证实。与其阿拉伯语的前身一样，奥斯蒂奇已经与中亚的姐妹语言分离了几千年，在非伊朗的环境中使用。它产生了某些特征，特别是由于邻近语言（突厥语，高加索语）的影响。这适用于词汇以及语音和语法结构。关于词汇借用，突厥语言的影响似乎特别强烈。

Ossetic belongs to the eastern branch of the Iranian family of languages. The linguistic ancestors of the present-day Ossetes were Alan tribes who, according to Greek and Roman sources, emigrated from Central Asia to the lands north and east of the Black Sea about the beginning of the Christian era (see ALANS, ASII). The Alans were, in their heyday in the early Middle Ages, a predominant people in the Northwest Caucasus, and their dialects were widespread in the area. The language was gradually ousted by Turkic and Cherkes immigrants from the west and north, and it is now limited to a relatively small region. There is some evidence that the present Ossetic-speaking area was formerly inhabited by Nakh-speaking (Ingush-Chechen, NE Caucasus) tribes. The previous presence of the Alans in the Northwest Caucasus is borne out by a number of place names of Iranian origin in modern Turkish and Cherkes areas. Ossetic, like its Alanic predecessor, has for millennia been separated from the sister languages of Central Asia, being spoken in non-Iranian surroundings. It has developed certain characteristic peculiarities, in part due to the influence of adjacent languages (Turkic, Caucasic). This applies to vocabulary as well as phonetic and grammatical structure. As regards lexical borrowing, the influence of Turkic languages seems to have been particularly strong.
