祖鲁语是南非11种官方语言中最大的语言之一，大约有900万人使用祖鲁语。它是一个以丰富的凝集形态结构为特征的语系的一部分。本文讨论了一种基于Xerox有限状态工具，特别是lexc和xfst的计算形态分析器的原型。除了考虑应用的形态策略和形态音素交替规则之外，重点是实现和其他需要解决的问题，以便为自动形态分析生成有用的软件工件。原型的当前状态通过提供形态学范围来暗示，即可以处理的各种单词类别（词性），以及根据分析器的嵌入式词典中包含的不同祖鲁词根的数量来表示的词汇覆盖。简要讨论了初步测试和验证程序。
As one of the largest of the 11 official languages of South Africa, Zulu is spoken by approximately 9 million people. It forms part of a language family which is characterized by rich agglutinating morphological structures. This paper discusses a prototype of a computational morphological analyzer for Zulu, built by means of the Xerox finite state tools, in particular lexc and xfst. In addition to considering both the morphotactics and the morphophonological alternation rules that apply, the focus is on implementation and other issues that need to be resolved in order to produce a useful software artefact for automated morphological analysis. The current status of the prototype is alluded to by providing morphological scope, that is the various word categories (parts of speech) that may be handled, and the lexical coverage in terms of the number of different Zulu roots that are included in the embedded lexicon of the analyzer. Preliminary testing and validation procedures are briefly discussed.
