In this article, I study clefts in Otomi, a small family of languages of Mexico from the Oto-Manguean stock. Clefts represent an area of Otomi syntax that has not been previously reported on. I compare the clefts we find in two very different languages: Tilapa Otomi and Northern Otomi. Clefts in Otomi are based on the copular construction and have three typologically expected elements (i.e., a copula, a focus phrase, and a relative-like clause encoding the common ground), but they also have two elements that are unique to Otomi: a pronominal enclitic that cross-references the focus phrase and a focus pronoun. The former is a property of the copular construction, but the latter only occurs in clefts. Clefts in Otomi also display a great amount of surface variation in natural discourse. In the article, I also explore the diachrony of the system by studying the historical sources from the colonial period.

Otomi 的裂缝：Copular 结构的扩展用途

在这篇文章中，我研究了 Otomi 的裂缝，Otomi 是一个来自 Oto-Manguean 种群的墨西哥语言小家族。裂口代表了以前没有报道过的 Otomi 语法领域。我比较了我们在两种截然不同的语言中发现的裂缝：Tilapa Otomi 和 Northern Otomi。Otomi 中的裂隙基于连接词结构，具有三个类型学上预期的元素（即连接词、焦点短语和编码共同点的类关系从句），但它们也有两个元素是 Otomi 独有的：代词 enclitic 交叉引用焦点短语和焦点代词。前者是copular结构的一个属性，但后者只出现在裂缝中。Otomi 的裂缝在自然话语中也显示出大量的表面变化。在文章中，
