This thesis analyzes English inquiry letters for online shopping from the perspective of systemic functional grammar. It begins with an introduction that outlines the study's rationale, aims, scope, methods, and design. The development section then reviews the theoretical background of systemic functional grammar and examines inquiry letters in terms of experiential, interpersonal, and textual meaning. Specifically, it analyzes transitivity, mood, and thematic structure. The study concludes by discussing implications for writing inquiry letters and suggesting exercises to practice this skill. It also acknowledges limitations and provides suggestions for further related research.
