当代网络口语中，新兴萌化AA叠词在语音、认知、人际及修辞层面实现了多维度语用增值。本文结合网络真实口语语料，系统分析新式AA叠词的四方面的语用增值机制。研究发现，萌化AA叠词通过情感、交互、视角与反讽增值实现功能增值，实现从传统语法构式到当代社交仪式的话语转型。这种语言创新本质上是数字时代青年群体适应媒介生态、构建审美化日常叙事的核心话语策略，为网络语体的演化与语言功能的变异研究提供了典型的样本。

In contemporary online spoken language, emerging moe-style AA reduplications achieve multi-dimensional pragmatic enhancement at phonetic, cognitive, interpersonal, and rhetorical levels. This paper systematically analyzes the four aspects of pragmatic value-added mechanisms of these new AA reduplications using authentic online spoken corpora. The study finds that moe-style AA reduplications achieve functional enhancement through emotional, interactive, perspectival, and ironic value addition, facilitating a discourse shift from traditional grammatical constructions to contemporary social rituals. This linguistic innovation fundamentally represents a core discourse strategy of digital-age youth in adapting to the media ecology and constructing aesthetically oriented everyday narratives, providing a representative example for research on the evolution of online registers and language function variation.
