This paper aims to demonstrate two things. First, Secoya (Tukanoan) has gender markers and shape classifiers. However, unlike other Tukanoan languages, Secoya does not display grammatical agreement, either between the head noun and its modifiers within a noun phrase or between the predicate and its arguments within a clause. Gender markers and shape classifiers are used in antecedent-anaphor relations. They appear in pronominal forms, demonstratives, and numerals to differentiate referents, playing a role in the way discourse is constructed and maintained. Second, a corpus study reveals that some traces of agreement might be emerging; however, it is currently restricted to one specific context, and there is significant speaker variation. Thus, Secoya is in a privileged position to inform debates regarding the mechanisms that may have given rise to complex classification systems in Northwest Amazonia, providing the missing link to understanding the interesting ways in which these different systems are related.

没有语法一致的名词分类：来自 Secoya 的证据

本文旨在证明两件事。首先，Secoya (Tukanoan) 有性别标记和形状分类器。然而，与其他 Tukanoan 语言不同，Secoya 不显示语法一致性，无论是在名词短语中的中心名词与其修饰语之间，还是在从句中的谓词与其论元之间。性别标记和形状分类器用于先行词-照应关系。它们以代词形式、指示词和数词出现，以区分所指对象，在话语的构建和维护方式中发挥作用。其次，一项语料库研究表明，可能会出现一些一致的迹象；然而，它目前仅限于一种特定的上下文，并且存在显着的说话者差异。因此，
