Abstract In this article we examine patterns of root allomorphy in Greek that involve vowel alternations and propose a Generalized Non-linear Affixation (Bermúdez-Otero 2012) analysis according to which these alternations result from the competition between segments that belong, on the one hand, to the vocabulary items of roots and, on the other, to the exponents of functional heads (Voice/Aspect, n). More specifically, we claim that phonological entities have a gradient degree of presence in a structure, that is, are specified with a certain activation strength value underlyingly (Smolensky and Goldrick 2016). As a result, the surface realization of roots is determined by the relevant activation level of the exponents of functional heads they are eventually combined with. From all available exponents, the one that optimally complements the strength value of the vocabulary item of a given root will eventually surface. Our analysis is shown to be theoretically advantageous because it develops a strictly phonological account of allomorphy and, moreover, it captures the attested generalizations without resorting to extensive stem/span listing or to the application of phonologically unrestricted readjustment rules.

根据强度改变形状：希腊文中根异形的证据

摘要在本文中，我们研究了希腊语中涉及元音交替的根同素异形模式，并提出了广义非线性附加（Bermúdez-Otero2012）分析，根据该分析，这些交替是由于属于不同部分的竞争而产生的，一方面，到词根的词汇项目，另一方面，到功能词的指数（Voice / Aspect，n）。更具体地说，我们声称语音实体在结构中具有梯度的存在度，也就是说，其潜在地具有一定的激活强度值（Smolensky and Goldrick 2016）。结果，根的表面实现取决于最终与之结合的功能头的指数的相关激活水平。从所有可用的指数中，最佳地补充给定根词汇量的强度值的那个最终将浮出水面。我们的分析在理论上是有优势的，因为它可以发展出严格的同音异义性语音说明，而且可以捕获经过证明的概括，而无需借助大量的词干/跨度列表或应用语音上不受限制的重新调整规则。
