Abstract Rutooro, a Bantu language spoken in western Uganda, exhibits two processes common to Bantu languages: Mid Vowel Harmony (MVH), by which a high vowel is lowered to mid if it follows a mid root vowel, and Consonant Mutation (CM), by which a high front vowel of certain morphemes trigger a change in the immediately preceding consonant. In forms where both rules could potentially apply, CM applies, but MVH does not, even though its structural description is met. Ultimately, it is shown that MVH is blocked when an alveolar fricative intervenes between the trigger and the target. The most anomalous forms are those that contain the short causative /-i/ and the Perfective suffix /-ir/. In some forms CM would be expected to apply, but does not, and in other forms MVH is expected to be blocked, but is not. The key to the analysis lies in the fact that CM is not a purely phonological process, but rather is only triggered by a small set of specific morphemes. The surface anomalies in the perfect forms can all be accounted for if one formalizes the relevant processes as only being triggered (or blocked) by unaltered [-ir].

Rutooro中未改变的语素作为语音触发和目标

摘要在乌干达西部使用的班图语Rutooro，展现出班图语共有的两个过程：中元音和声（MVH），如果跟随中根元音，则将高元音降低到中音；而辅音变异（CM），某些语素的高位元音通过它触发紧接在前辅音的变化。在可能同时适用这两种规则的形式中，CM适用，但MVH不适用，即使满足其结构描述。最终表明，当肺泡擦音插入触发器和目标之间时，MVH被阻断。最异常的形式是包含短因果关系/ -i /和完美后缀/ -ir /的形式。在某些形式中，预期CM将适用，但在某些形式中，预期MVH将被阻止，但并非如此。分析的关键在于以下事实：CM不是纯粹的语音过程，而是仅由一小组特定的语素触发的事实。如果将相关过程正式化为仅由未更改的[-ir]触发（或阻止），则可以以完美形式解决表面异常。
