One of the most controversial aspects of Hittite phonology is the question of the significance, if any, of the so-called plene-writing of vowels. Explanations for this practice have been sought in a variety of directions. Some have seen in it the continuation of a tradition inherited from predecessors of the Hittite cuneiform syllabary with perhaps little relevance to the facts of the Hittite language. Others have been more confident in seeing in it a method of representing some real linguistic feature, such as vowel length, while inconsistencies or apparent inconsistencies in its use have led others to the conclusion that it has often no functional significance at all. No full-scale investigation of the phenomenon covering the entire Hittite corpus has yet been carried out, nor is such an attempt practicable here. The present paper has the restricted aim of investigating one particular phenomenon, the occurrence of plene-writing in different syllables in different inflexional forms of the same words, and the material drawn upon is chiefly Old and Middle Hittite, since it seems likely that certain patterns of variation in the use of plene-writing were quite early disturbed by analogical levelling within paradigms, or eliminated by the abandonment of plene-writing in the words in question; nevertheless, I believe that the oldest texts in particular still preserve enough evidence for these patterns to be discernible and that the reasons for them are intelligible in historical terms.
