Metalanguage refers to language used to describe, analyze, or discuss another language or aspects of language itself ^[1]. In linguistics, metalanguage consists of specialized terms, concepts, and symbolic systems that enable the formal description of linguistic structures, including sounds, words, grammatical patterns, and meanings ^[2]. It is distinguished from object language, which is the language being analyzed, whereas metalanguage functions as the descriptive framework through which properties and relations within the object language are examined ^[1]. Metalanguage may be expressed through ordinary linguistic forms or through technical notation developed for linguistic analysis and theoretical description ^[3].
