The document presents a presentation on Systemic Functional Linguistics (SFL) by Laiba Yaseen, detailing its significance in language acquisition, education, and discourse analysis. SFL, developed by M.K.A. Halliday, focuses on how language functions to convey meaning within various contexts, emphasizing the interrelation between language and context through metafunctions. The approach is crucial in Second Language Acquisition (SLA) as it helps learners analyze grammatical features, contextualize texts, and enhance their writing skills.
