A writing system is a conventionalized system of graphic signs and rules that represents linguistic units through visual symbols, enabling the encoding and interpretation of spoken language or other structured linguistic information ^[1]. It consists of an inventory of signs and the principles governing their relationship to linguistic elements, including the ways in which symbols represent phonological, morphological, lexical, or semantic units ^[1][2]. Within linguistics, writing systems are distinguished from scripts, which refer primarily to the graphical forms and sign repertoires used in writing, because a writing system includes both the script and the representational principles that determine how written signs correspond to language ^[2]. Writing systems may therefore be classified according to the level of linguistic structure represented by their signs, such as alphabetic, syllabic, or logographic organization ^[1][2].
