👉 Sublanguage is a linguistic concept that refers to languages with a unique set of rules and structures that are not part of the dominant language spoken in a particular region. These languages may have their own grammatical, phonological, syntactic, or semantic features that distinguish them from other languages. In contrast to a dominant language, sublanguages often display a more complex structure, such as multiple sentence structures, affixes, and verb tenses, which allow for the creation of new words and expressions.
