The Yucatec Maya language has a highly complex deictic system with interesting typological differences that in addition to demonstratives and locative adverbs also includes ostensive evidentials and modal adverbs. Given that deictic words are among the first that children produce, the aim of this study is to identify the early acquisition that Yucatec Mayan children follow to map out each deictic form. Deictic words taken from spontaneous, longitudinal, transversal corpora and Gaskins's (1990) field work annotations were labeled and analyzed. The results show that children begin by uttering protoforms mapped with prototypical functions of locative and modal adverbs, but the functions of both demonstratives and ostensive evidentials are expressed mostly with the same protoform, which is similar to the deictic organizations of other languages. When children become productive, they overextend functions, which demonstrates a reanalysis of the system before acquisition is complete.

获取尤卡特克玛雅指示系统的萌芽、早期发展和创造力

Yucatec Maya 语言具有高度复杂的指示系统，具有有趣的类型差异，除了指示副词和地方副词外，还包括明示证据和情态副词。鉴于指示词是儿童最先产生的，本研究的目的是确定尤卡特克玛雅儿童遵循的早期习得以绘制每种指示形式。从自发的、纵向的、横向的语料库和 Gaskins (1990) 的田野工作注释中提取的指示词被标记和分析。结果表明，孩子们首先说出的原型与位置副词和情态副词的原型功能相对应，但指示性和明示性证据的功能大多使用相同的原型来表达，这与其他语言的指示组织相似。
