Studies of multilingual systems found in Indigenous small-scale communities often assume that exogamous marriages are the norm in such societies and contribute to their linguistic diversity. This paper is an account of the language ideology of endogamous societies in rural highland Daghestan (Northeast Caucasus). By studying language policing and language choice in infrequent mixed marriages, the paper uncovers the beliefs that support endogamy and reveals issues of linguistic identity and attitudes toward the usage of the matrilect within the family and the village. Interviews show that in-married women do not bring new languages to the villages, because they quickly acquire the local language new to them and use it with all their in-laws and their children. A strong association between villages and languages together with the ideology supporting linguistic homogeneity within the village contributes to the maintenance of the regional linguistic diversity.

内婚社会中的语言意识形态：以达吉斯坦为例

对土著小规模社区中发现的多语言系统的研究通常假设外婚婚姻是此类社会的常态，并有助于其语言多样性。本文是对农村高地达吉斯坦（东北高加索）内婚社会的语言意识形态的描述。通过研究罕见的混合婚姻中的语言监管和语言选择，本文揭示了支持内婚制的信念，并揭示了语言身份问题以及家庭和村庄对使用母系通婚的态度。访谈显示，已婚妇女并没有将新语言带到村庄，因为她们很快就掌握了当地的新语言，并与所有的公婆和孩子一起使用。
