academic tweets in applied linguistics: an intertextuality odyssey through forms and functions in five english-speaking countries

Social media platforms, particularly twitter, have transformed how academics communicate, disseminate research, and engage with broader audiences. this study explored intertextuality within academic tweets crafted by applied linguists across five english-speaking countries: the united states, the united kingdom, australia, canada, and ireland. by analyzing tweets from prominent applied linguistics associations, the research identified intertextual representations and examined how they refer to or incorporate other texts. the study used a qualitative approach to uncover the forms and functions of intertextuality, highlighting the complex relationships between texts and social actors on twitter. a corpus of 300 tweets from major associations in applied linguistics provided a rich dataset for analysis. key findings indicated that intertextual practices in academic tweets are crucial for self-promotion, publicizing research outputs, and building academic communities. multimodal quotations, digital mentions, and hyperlinks enhance engagement, extend reach, and provide additional context. tweets served multiple functions, including community building, networking, and public dissemination of academic knowledge. the study highlighted the evolving nature of academic communication on social media, suggesting that applied linguistics groups strategically use twitter to enhance their scholarly presence and impact. practical implications included the strategic use of hashtags, multimodal elements, and active engagement through retweets, mentions, and replies, which improve visibility, impact, and foster a sense of community within the field.
