Specialized Language Instruction refers to a domain-oriented approach to language education that focuses on developing learners’ linguistic competence for specific professional, academic, or disciplinary contexts rather than general-purpose communication [1]. It is characterized by the systematic selection and organization of language knowledge, communicative practices, and instructional objectives according to the discourse conventions, communicative purposes, and literacy requirements of a particular field or community [1][2]. The concept differs from general language instruction in that it is defined by its alignment with the specialized communicative needs and practices of a specific domain, while also overlapping with approaches such as English for Specific Purposes (ESP), which emphasize the relationship between language learning and target-context requirements [2].
