This paper describes two different grammatical tone constructions that occur in the verb morphology of Tenango Otomi (Central Mexico; Oto-Pamean, Oto-Manguean), which consist in tone alternations on the verb stem that are conditioned by aspect, transitivity, inflectional class, and prosody; furthermore, the specific alternation patterns a verb undergoes are lexically stipulated. These two constructions combine to form 19 different tone classes (i.e., groups of verbs that follow similar tone alternation patterns). I describe these constructions in terms of two of the more recent typologies of grammatical tone phenomena (Palancar 2016; Rolle 2018), and I discuss how the analysis of verb inflection in Tenango Otomi contributes to such typologies. Furthermore, I propose two different accounts for the apparent irregularities in the inflection system presented, one based on (morpho)phonological rules and another one based on a word-and-paradigm model.

Tenango Otomi 中的动词变形和语法声调的类型学

本文描述了 Tenango Otomi（墨西哥中部；Oto-Pamean，Oto-Manguean）动词形态中出现的两种不同的语法声调结构，它们包括动词词干上的音调变化，这些变化受方面、及物性、屈折类、和韵律；此外，动词所经历的特定交替模式是词汇上规定的。这两种结构组合形成 19 个不同的声调类别（即遵循相似声调交替模式的动词组）。我根据两种最近的语法音调现象类型（Palancar 2016；Rolle 2018）来描述这些结构，并讨论 Tenango Otomi 中动词屈折变化的分析如何促成这种类型。此外，
