This paper examines the different functions of bale (‘yes’) in Persian by identifying its positions in the syntagmatic chain. As such, it reveals a significant correlation exists between the function types, various positions, and the frequency of bale, which appears on the left periphery (LP), on the right periphery (RP), and in the medial, detached or free-standing mode at a rate of 20.5%, 9.5, 2.1%, and 67.9%, respectively. On LP, it can function for all the three types (e.g. propositional, textual, and interpersonal) involved in it. Besides, on LP it is generally associated with textual and subjective usages, but its position on RP can be explained in terms of intersubjectivity. The function of bale as a detached thetical is argued to be predominant in an intersubjective phenomenon motivated by paying attention to/from the addressee. Furthermore, a diachronic survey of the bale development suggests that it has started as a connective, a confirmative, or an emphatic response markers on LP; then, it has moved to RP to fulfill more intersubjective usages.

波斯语话语中的包（“是”）方面：它的功能、位置和演变*

本文通过确定其在组合链中的位置来研究波斯语中bale（“是”）的不同功能。因此，它揭示了功能类型、不同位置和出现在左边缘 (LP)、右边缘 (RP) 以及内侧、分离或自由的包块频率之间存在显着相关性。站立模式的比率分别为 20.5%、9.5、2.1% 和 67.9%。在 LP 上，它可以对其中涉及的所有三种类型（例如命题、文本和人际）起作用。此外，在 LP 上，它通常与文本和主观用法相关联，但它在 RP 上的位置可以用主体间性来解释。捆包的作用作为一种超然的理论，被认为在一种主体间现象中占主导地位，这种现象的动机是关注/来自收件人。此外，对棉包发展的历时调查表明，它已开始作为 LP 上的连接、确认或强调响应标记；然后，它已经转移到 RP 以实现更多的主体间用法。
