Cross-linguistically, morphomes are empirically robust but there are few well-studied cases outside of Romance. We analyze the distribution of present and aorist stems in Western Armenian, an understudied Indo-European language. Canonically, the aorist encodes perfective aspect, but it is meaninglessly used in different paradigm cells for different conjugation classes. For these meaningless cases, the aorist stem acts as a morphomic item. The shape of the aorist stem varies across conjugation classes, including regular classes that use a dedicated aorist suffix vs. irregular classes that use root suppletion. This parallelism across the regular and irregular verbs further establishes that the aorist stem is a legitimate morphological item, and not just a set of homophonous items. We formalize the data in Distributed Morphology, a post-syntactic morphological framework. We use head-insertion or node-sprouting to model how the aorist suffix has canonical perfective semantics, but it is meaninglessly inserted by the morphology in non-perfective contexts. We find that the creation of the aorist stem occurs early in the derivation, and it cyclically interacts with allomorphy and morphophonological alternations. In sum, the morphomic aorist is well-integrated into Armenian morphotactics, and morphomic elements interact with other morphological operations.

从跨语言的角度来看，语素在经验上是稳健的，但除了浪漫之外，很少有经过充分研究的案例。我们分析了西方亚美尼亚语中现在和不定过去时词干的分布，这是一种未被充分研究的印欧语系。典型地，不定过去时编码完成方面，但它在不同的范式单元中用于不同的共轭类是毫无意义的。对于这些无意义的情况，不定过去时词干充当词素项。不定过去时词干的形状因共轭类而异，包括使用专用不定过去时后缀的常规类与使用词根补缀的不规则类。规则动词和不规则动词之间的这种平行性进一步确定了不定过去时词干是一个合法的形态项目，而不仅仅是一组同音项目。我们将分布式形态学中的数据形式化，后句法形态框架。我们使用 head-insertion 或 node-sprouting 来模拟不定过去时后缀如何具有规范的完美语义，但它在非完美语境中被形态无意义地插入。我们发现不定过去时词干的产生发生在派生的早期，并且它周期性地与同形异形和形态音位交替相互作用。总之，形态不定过去时很好地融入了亚美尼亚形态趋化，形态元素与其他形态操作相互作用。并且它周期性地与同种异形和形态语音交替相互作用。总之，形态不定过去时很好地融入了亚美尼亚形态趋化，形态元素与其他形态操作相互作用。并且它周期性地与同种异形和形态语音交替相互作用。总之，形态不定过去时很好地融入了亚美尼亚形态趋化，形态元素与其他形态操作相互作用。
