<![CDATA[Members of Generation Z have a tendency to mix English elements into Indonesian-language Instagram posts and comments. This phenomenon is worthy of attention for both its linguistic form and the intent and social context behind its use. This study therefore places code-mixing within a sociopragmatic framework, viewing language choice as part of a speaker’s strategy for adapting to the addressee, topic, and context in digital spaces. The study aims to describe the forms of code-mixing and the linguistic elements mixed, along with their source languages, as well as the sociopragmatic intent behind their use. The approach used is descriptive and qualitative. Data consist of 30 quotations of Generation Z Instagram posts and comments taken from a single source file and treated as a secondary corpus. These were analysed through identification and classification of forms based on Suwito’s code-mixing theory, followed by interpretation of speech intent in relation to the addressee, topic, and platform context. Established loanwords were not counted as code-mixing. The analysis shows that the most frequent form is word insertion (19 occurrences), followed by phrases (9), clauses (4), expressions (4), and hybrids (2), with no instances of reduplication. All inserted elements originate from English and are used to intensify emotion, greet others, mark generational identity, and convey intent concisely and informally, in line with the social context of Instagram.]]>
