Abstract
This study aims to analyze the vocabulary used in online shop activities on Instagram social media and examine its contribution to Indonesian language learning. Through a qualitative-descriptive approach, data is collected from uploads and product descriptions on several popular online shop accounts . The results of the analysis show that the vocabulary used reflects a mixture of non-standard Indonesian, foreign absorption (especially English), abbreviations, and popular terms (slang) that are developing in online communities. The collection of data is sourced from 5 (five) Online Shops, namely @omorfoo_shop, @bunoshopp28, @sental.kaos, @akavi.id, and @citracosmetic_id. The contribution to Indonesian learning lies in the potential use of authentic context from social media as teaching materials, especially in learning language diversity, vocabulary development, and language attitudes.
