A major challenge presented by noun class systems of Senufo languages is the non-trivial interaction between the agreement features of the noun phrase and the noun class specification on the head noun. In Kafire (Senufo, Côte d’Ivoire), demonstratives normally agree with the head noun independent of whether or not the head noun is modified by adjectives. Some adjectives, however, are exceptions to the general rule: in their presence the demonstrative appears in Class 2 or 3 (depending on the adjective), and fails to agree with the head noun. We present an account of the exceptional behavior of such adjectives within the framework of Lexical-Functional Grammar. We show that agreement in Kafire is a heterogeneous phenomenon that is best viewed as transitional between a system of semantically motivated agreement and a system of noun classes that is no longer dependent on meaning. Vestiges of the old system have been preserved in a variety of phenomena that have to be addressed individually using different kinds of formal tools provided by the framework. The variety of formal devices required to describe the functioning of the agreement system reflects the complex diachrony and the cross-modal (lexico-syntactic) synchronic nature of agreement phenomena.

Senufo 语言的名词类系统面临的一个主要挑战是名词短语的一致特征与头部名词的名词类规范之间的非平凡交互。在 Kafire (Senufo, Côte d'Ivoire) 中，指示词通常与中心名词一致，与中心名词是否被形容词修饰无关。然而，一些形容词是一般规则的例外：在它们的存在下，指示词出现在第 2 类或第 3 类（取决于形容词），并且与中心名词不一致。我们在词汇功能语法的框架内介绍了这些形容词的特殊行为。我们表明，Kafire 中的一致性是一种异质现象，最好将其视为语义动机一致性系统和不再依赖于意义的名词类系统之间的过渡。旧系统的痕迹已经保存在各种现象中，这些现象必须使用框架提供的不同种类的正式工具单独解决。描述协议系统功能所需的各种形式设备反映了协议现象的复杂历时性和跨模态（词汇句法）同步性质。
