This study investigates the pragmatic functions of emojis as multimodal resources in students' interactions on Facebook, Twitter (X), and Reddit, with a focused distinction between politeness and sarcasm. Drawing on a corpus of 4000 naturally occurring student-generated posts (Facebook: 1200; Twitter/X: 1500; Reddit: 1300), the study applies a qualitative-quantitative coding framework grounded in Brown and Levinson's politeness theory and Gricean pragmatic models. Emojis are analyzed as components of semiotic bundles rather than isolated affective markers. Statistical analysis reveals significant gendered patterns (χ 2 (1, N = 420) = 89.2, p < 0.001), with female students demonstrating greater use of emojis for politeness and solidarity functions (70.0%) compared to male students (35.0%), while male students show higher utilization for sarcasm and irony (65.0%) versus female students (30.0%). Platform-specific affordances significantly shape these pragmatic functions, with Facebook favoring politeness strategies, Reddit enabling ironic communication through anonymity, and Twitter facilitating compressed evaluative expressions. The findings suggest that emoji competence constitutes a fundamental component of digital pragmatic literacy requiring integration into higher education curricula.
