Abstract Over the past several decades there has been recurrent skeptism concerning cyclic derivations in phonology, one of the most central tenets of traditional generative and lexical phonology and morphology. In this paper I draw on original data from Lulamogi, a previously almost unstudied Bantu language of Uganda, to show that the most insightful analysis of some rather unusual vowel length alternations requires either cyclicity or global reference to internal morphological structure, specifically the difference between stem vs. prefix V+V sequences. After documenting the vowel length properties in some detail I consider several analyses, opting for a stratal account which neatly mirrors the traditional Bantu stem, word, and phrasal domains.

Lulamogi中的元音前缀长度：层状记帐

摘要在过去的几十年中，关于音位学中循环派生的反复出现的怀疑论是传统的生成和词汇音位学和形态学的最主要宗旨之一。在本文中，我借鉴了乌拉达语以前几乎未被研究的Lulamogi的原始数据，以表明对某些相当不寻常的元音长度变化的最有见地的分析需要周期性或全局参考内部形态结构，特别是词干之间的差异与前缀V + V序列。在详细记录了元音长度属性后，我考虑了几种分析方法，选择了能清晰反映出传统班图语词干，词素和短语域的层状账目。
