Abstract Characterized by the dynamic interplay between English and Filipino, the Philippine linguistic landscape has given rise to "Conyo," a linguistic phenomenon characterized by the code-mixing of English and Filipino, also called "Taglish". This article investigated whether Conyo serves as a communicative advantage (boon) or a hindrance (bane) for Senior High School learners at Christ the King College de Maranding. Employing a mix of quantitative descriptive-correlational research design and qualitative analysis, the study utilized surveys to assess the language practices of 30 randomly selected respondents and analyzed the data against their socio-demographic profiles using statistical tests. The main findings revealed that students possess a high level of sociolinguistic competence, using Conyo as a pragmatic tool for clearer self-expression without significant influence from their gender, economic status, or academic background. Ultimately, the study concludes that Conyo acts as a boon by lowering linguistic anxiety and fostering social solidarity, recommending its integration into pedagogical strategies.
