This paper discusses historical and ongoing morphological simplification in Alorese, an Austronesian language spoken in eastern Indonesia. From comparative evidence, it is clear that Alorese lost almost all of its morphology over several hundred years as a consequence of language contact (Klamer, 2012, to appear). By providing both linguistic and cultural-historical evidence, this paper shows that Alorese has historically undergone morphological simplification as a result of second language (L2) learning. The first part of the paper presents a case study comparing the use of subject agreement prefixes in Alorese L1 speakers (n=6) and Alorese L2 speakers (n=12). The results show that L2 speakers deviate from the native norm, and tend to use one prefix as default agreement. The variation found among L2 speakers reveals an ongoing change possibly leading to the restructuring of the Alorese agreement system. The second part of the paper applies models of linguistic change (Kusters, 2003; Trudgill, 2011) to the Alorese community and shows that Alorese has been, and still is, spoken in a community with a large number of L2 speakers, where morphological simplification is expected to occur.

阿洛雷斯语（南岛语）的形态学损失：成人语言接触的简化

本文讨论了在印度尼西亚东部使用的南岛语言 Alorese 的历史和正在进行的形态简化。从这个证据中可以明显看出，由于语言接触，比较性的阿洛里斯语在数百年中几乎失去了所有的形态（Klamer，2012，出现）。通过提供语言和文化历史证据，本文表明阿洛雷斯历史上由于第二语言 (L2) 学习而经历了形态简化。本文的第一部分介绍了一个案例研究，比较了阿罗拉 L1 说话者（n = 6）和阿罗拉 L2 说话者（n = 12）中主题一致前缀的使用。结果表明，L2 说话者偏离母语规范，倾向于使用一个前缀作为默认协议。在 L2 说话者中发现的差异揭示了可能导致阿洛雷斯协议系统重组的持续变化。论文的第二部分将语言变化模型（Kusters，2003 年；Trudgill，2011 年）应用于 Alorese 社区，并表明 Alorese 已经并且仍然在一个拥有大量 L2 使用者的社区中使用，其中形态简化预计会发生。
