Tocharian had a large number of demonstrative pronouns and determiners, whose basic element derives from the Proto-Indo-European genderdifferentiated pronoun *so (masc.), *seh2 (fem.), *tod (nt.) ‘this, that’. This article is chiefly concerned with the diachronic evolution of the endings and forms of these demonstratives, paying particular attention to the inflection of the feminine and the subsequent evolution of the category of gender. I argue that the feminine plural paradigm of both Tocharian A and B can be derived directly from Proto-Indo-European, with further analogical adjustments within Tocharian B.

论吐火罗语中代词阴性复数

Tocharian 有大量指示代词和限定词，其基本元素来源于原始印欧语的性别分化代词 *so (masc.), *seh2 (fem.), *tod (nt.) 'this, that'。本文主要关注这些指示词的词尾和形式的历时演变，特别关注阴性词的屈折变化以及随后的性别范畴的演变。我认为 Tocharian A 和 B 的女性复数范式都可以直接从原始印欧语系派生而来，并在 Tocharian B 中进行了进一步的类比调整。
