", "\nAbstract\nThis article introduces the concept of vernacular infrastructuring to examine how speakers of minoritized languages navigate multilingual digital environments. Building on notion of vernacular creativity and extending insights from linguistic anthropology, I conceptualize infrastructuring as the everyday negotiation of institutional norms, platform logics, and user practices that structure linguistic visibility. Drawing on the case of Nanti Kita Sambat tentang Hari Ini (NKSTHI), a popular Instagram and X account that reimagines the Javanese speech genre sambat (“to complain”), I show how users creatively mobilize Javanese to perform cultural intimacy while tactically responding to algorithmic imaginaries. I argue that vernacular infrastructuring operates through three entangled layers: institutional infrastructures (historical hierarchies of language policy and media), perceived platform infrastructures (folk theories and algorithmic imaginaries), and user practices (stylization, code‐mixing, and affective design). Through this layered analysis, the paper demonstrates that vernacular practices are not merely expressive but infrastructurally strategic forms of discursive value work, referring to the speakers' reflexivity to assign and contest linguistic value. By foregrounding the agentive tactics of minoritized users, vernacular infrastructuring contributes to ongoing debates in linguistic anthropology on language, media, and infrastructure, showing how digital platforms actively participate in the revaluation of linguistic diversity.\n\nAbstrak\nArtikel menika ngenalaken teori “praktik infrastruktur vernakular” kagem mahami cara penutur basa minoritas menavigasi lingkungan digital multibahasa. Kanthi dasar gagasan bab kreativitas vernakular lan nambah kawruh saking linguistik antropologi, kula njabaraken konsep “infrastruktur” minangka negosiasi norma kelembagaan, logika platform, lan praktik panganggenan platform digital ingkang mbentuk visibilitas linguistik. Sangking kasus Nanti Kita Sambat Tentang Hari Ini (NKSTHI), akun instagram lan X babagan “sambat”, kula nedahi pangangge kaliyan mobilisasi kreatif basa jawi kangge nampilaken keintiman budaya merespon imajinasi algoritmik. Kula nggadahi pemanggih menawi infrastruktur vernakular kedah nglangkungi tigang lapisan kekait: infrastruktur kelembagaan (hierarki historis kebijakan basa lan media), infrastruktur platform ingkang dipersepsikan (teori rakyat lan imajinasi algoritmik), lan praktik pangangge basa (stilisasi, campur kode, lan desain afektif). Liwat analisis berlapis puniki, kula nunjukaken menawi praktik vernakular sanes naming ekspresif, ananging bentuk‐bentuk strategis infrastruktural saking nilai sosial ingkang gadhah sipat diskursif, ingkang ngrujuk ing refleksivitas penutur lebet netepaken lan memperdebatkan nilai sosial basa. Kanthi ngutamaaken taktik agensi pengguna basa minoritas, teori infrastruktur vernakular gadhahi kontribusi ing perdebatan teori lebeting bidang linguistik antropologi bab basa, media, lan infrastruktur, nedahaken kados pundi platform digital tumut gadhahi peran lebet revaluasi karagaman basa ing jagad digital.\n"]
