This paper demonstrates that morphological change tends to involve the replacement of low frequency forms in inflectional paradigms by innovative forms based on high frequency forms, using Greek data involving the diachronic reorganisation of verbal inflection classes. A computational procedure is outlined for generating a possibility space of morphological changes which can be represented as analogical proportions, on the basis of synchronic paradigms in ancient Greek. I then show how supplementing analogical proportions with token frequency information can help to predict whether a hypothetical change actually took place in the language’s subsequent development. Because of the crucial role of inflected surface forms serving as analogical bases in this model, I argue that the results support theories in which inflected forms can be stored whole in the lexicon.

令牌频率作为形态变化的决定因素

本文表明，形态变化往往涉及用基于高频形式的创新形式取代屈折范式中的低频形式，使用涉及动词屈折类的历时重组的希腊数据。基于古希腊的共时范式，概述了一种计算过程，用于生成可以表示为类比比例的形态变化的可能性空间。然后，我展示了用标记频率信息补充类比比例如何有助于预测在语言的后续发展中是否真的发生了假设的变化。由于在该模型中作为类比基础的变形曲面形式的关键作用，
