In this paper, I present an analysis of pseudo-ABA patterns of morphology found in pronominal forms. I argue that an analysis that assumes unrestricted phonologically null allomorphy or unrestricted impoverishment overgenerates, allowing all the logically possible patterns of syncretism to appear. An analysis that includes spanned portmanteau exponents generates all and only the attested patterns of syncretism. Pseudo-ABA patterns arise when the complete pronominal tree (the structure for the anaphor) is exponed by a spanned exponent for [a [d]] and an exponent for p. Spanned portmanteau exponents are compatible with an analysis in which a and d are cyclic nodes, and one in which they are not. However, the analysis in which a and d are cyclic nodes is incompatible with another morphological behaviour of pronominal forms, namely variable exponence. To provide a unified analysis of pseudo-ABA patterns and variable exponence, a and d cannot be cyclic nodes.

在本文中，我对代词形式中的伪 ABA 形态模式进行了分析。我认为，假设无限制的音系零同质异形或无限制的贫困化的分析会过度生成，从而允许所有逻辑上可能的融合模式出现。包含跨度组合指数的分析会生成所有且仅经过证实的融合模式。当完整的代词树（照应词的结构）由 [ a [ d ]] 的跨度指数和p的指数展开时，伪 ABA 模式就会出现。跨度混合指数与a和d是循环节点的分析兼容，而在 a 和 d 不是循环节点的分析中则兼容。然而， a和d是循环节点的分析与代词形式的另一种形态行为（即变量指数）不相容。为了提供伪 ABA 模式和变量指数的统一分析，a和d不能是循环节点。
