This article introduces an approach that middle-school teachers can follow to help their students carry out linguistic-based literary analyses. As an example, it draws on Systemic Functional Grammar (SFG) to show how J.K. Rowling used language to characterize Hermione as an intelligent female in "Harry Potter and the Deathly Hallows." Using a simplified SFG analysis, the authors show how teachers can help students find and use language data that can support their intuition about characters or can uncover other patterns in the text. This type of SFG analysis approach can be particularly useful for English language learners and struggling readers as it provides students with useful tools for text analysis.
